mfd: max77843: Fix max77843_chg_init() return on error

2015-10-01T15:31:42Z

If i2c_new_dummy() fails in max77843_chg_init(), an PTR_ERR(NULL) is returned which is 0. So the function was wrongly returning a success value instead of an error code.

mfd: intel-lpss: Fix build error when !CONFIG_PM_SLEEP

2015-10-01T15:31:33Z

Jim Davis reported the compilation error with a random configuration which apparently has CONFIG_PM=y and CONFIG_PM_SLEEP=n. With that conditions we have missed definition of INTEL_LPSS_SLEEP_PM_OPS macro. Add it here. Reported-by: Jim Davis Signed-off-by: Andy Shevchenko Signed-off-by: Lee Jones

genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51Z

Most interrupt flow handlers do not use the irq argument. Those few which use it can retrieve the irq number from the irq descriptor. Remove the argument. Search and replace was done with coccinelle and some extra helper scripts around it. Thanks to Julia for her help! Signed-off-by: Thomas Gleixner Cc: Julia Lawall Cc: Jiang Liu

Pull sound updates from Takashi Iwai: "There are little changes in core part, but lots of development are found in drivers, especially ASoC. The diffstat shows regmap-related changes for a slight API additions / changes, and that's all. Looking at the code size statistics, the most significant addition is for Intel Skylake. (Note that SKL support is still underway, the codec driver is missing.) Also STI controller driver is a major addition as well as a few new codec drivers. In HD-audio side, there are fewer changes than the past. The noticeable change is the support of ELD notification from i915 graphics driver. Thus this pull request carries a few changes in drm/i915. Other than that, USB-audio got a rewrite of runtime PM code. It was initiated by lockdep warning, but resulted in a good cleanup in the end. Below are the highlights: Common: - Factoring out of AC'97 reset code from ASoC into the core helper - A few regmap API extensions (in case it's not pulled yet) ASoC: - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek RT298 and ST STI controllers - Machine drivers for Rockchip systems with MAX98090 and RT5645 and RT5650 - Initial driver support for Intel Skylake devices - Lots of rsnd cleanup and enhancements - A few DAPM fixes and cleanups - A large number of cleanups in various drivers (conversion and standardized to regmap, component) mostly by Lars-Peter and Axel HD-audio: - Extended HD-audio core for Intel Skylake controller support - Quirks for Dell headsets, Alienware 15 - Clean up of pin-based quirk tables for Realtek codecs - ELD notifier implenetation for Intel HDMI/DP USB-audio: - Refactor runtime PM code to make lockdep happier" * tag 'sound-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (411 commits) drm/i915: Add locks around audio component bind/unbind drm/i915: Drop port_mst_index parameter from pin/eld callback ALSA: hda - Fix missing inline for dummy snd_hdac_set_codec_wakeup() ALSA: hda - Wake the codec up on pin/ELD notify events ALSA: hda - allow codecs to access the i915 pin/ELD callback drm/i915: Call audio pin/ELD notify function drm/i915: Add audio pin sense / ELD callback ASoC: zx296702-i2s: Fix resource leak when unload module ASoC: sti_uniperif: Ensure component is unregistered when unload module ASoC: au1x: psc-i2s: Convert to use devm_ioremap_resource ASoC: sh: dma-sh7760: Convert to devm_snd_soc_register_platform ASoC: spear_pcm: Use devm_snd_dmaengine_pcm_register to fix resource leak ALSA: fireworks/bebob/dice/oxfw: fix substreams counting at vmalloc failure ASoC: Clean up docbook warnings ASoC: txx9: Convert to devm_snd_soc_register_platform ASoC: pxa: Convert to devm_snd_soc_register_platform ASoC: nuc900: Convert to devm_snd_soc_register_platform ASoC: blackfin: Convert to devm_snd_soc_register_platform ASoC: au1x: Convert to devm_snd_soc_register_platform ASoC: qcom: Constify asoc_qcom_lpass_cpu_dai_ops ...

Pull power management and ACPI updates from Rafael Wysocki: "From the number of commits perspective, the biggest items are ACPICA and cpufreq changes with the latter taking the lead (over 50 commits). On the cpufreq front, there are many cleanups and minor fixes in the core and governors, driver updates etc. We also have a new cpufreq driver for Mediatek MT8173 chips. ACPICA mostly updates its debug infrastructure and adds a number of fixes and cleanups for a good measure. The Operating Performance Points (OPP) framework is updated with new DT bindings and support for them among other things. We have a few updates of the generic power domains framework and a reorganization of the ACPI device enumeration code and bus type operations. And a lot of fixes and cleanups all over. Included is one branch from the MFD tree as it contains some PM-related driver core and ACPI PM changes a few other commits are based on. Specifics: - ACPICA update to upstream revision 20150818 including method tracing extensions to allow more in-depth AML debugging in the kernel and a number of assorted fixes and cleanups (Bob Moore, Lv Zheng, Markus Elfring). - ACPI sysfs code updates and a documentation update related to AML method tracing (Lv Zheng). - ACPI EC driver fix related to serialized evaluations of _Qxx methods and ACPI tools updates allowing the EC userspace tool to be built from the kernel source (Lv Zheng). - ACPI processor driver updates preparing it for future introduction of CPPC support and ACPI PCC mailbox driver updates (Ashwin Chaugule). - ACPI interrupts enumeration fix for a regression related to the handling of IRQ attribute conflicts between MADT and the ACPI namespace (Jiang Liu). - Fixes related to ACPI device PM (Mika Westerberg, Srinidhi Kasagar). - ACPI device registration code reorganization to separate the sysfs-related code and bus type operations from the rest (Rafael J Wysocki). - Assorted cleanups in the ACPI core (Jarkko Nikula, Mathias Krause, Andy Shevchenko, Rafael J Wysocki, Nicolas Iooss). - ACPI cpufreq driver and ia64 cpufreq driver fixes and cleanups (Pan Xinhui, Rafael J Wysocki). - cpufreq core cleanups on top of the previous changes allowing it to preseve its sysfs directories over system suspend/resume (Viresh Kumar, Rafael J Wysocki, Sebastian Andrzej Siewior). - cpufreq fixes and cleanups related to governors (Viresh Kumar). - cpufreq updates (core and the cpufreq-dt driver) related to the turbo/boost mode support (Viresh Kumar, Bartlomiej Zolnierkiewicz). - New DT bindings for Operating Performance Points (OPP), support for them in the OPP framework and in the cpufreq-dt driver plus related OPP framework fixes and cleanups (Viresh Kumar). - cpufreq powernv driver updates (Shilpasri G Bhat). - New cpufreq driver for Mediatek MT8173 (Pi-Cheng Chen). - Assorted cpufreq driver (speedstep-lib, sfi, integrator) cleanups and fixes (Abhilash Jindal, Andrzej Hajda, Cristian Ardelean). - intel_pstate driver updates including Skylake-S support, support for enabling HW P-states per CPU and an additional vendor bypass list entry (Kristen Carlson Accardi, Chen Yu, Ethan Zhao). - cpuidle core fixes related to the handling of coupled idle states (Xunlei Pang). - intel_idle driver updates including Skylake Client support and support for freeze-mode-specific idle states (Len Brown). - Driver core updates related to power management (Andy Shevchenko, Rafael J Wysocki). - Generic power domains framework fixes and cleanups (Jon Hunter, Geert Uytterhoeven, Rajendra Nayak, Ulf Hansson). - Device PM QoS framework update to allow the latency tolerance setting to be exposed to user space via sysfs (Mika Westerberg). - devfreq support for PPMUv2 in Exynos5433 and a fix for an incorrect exynos-ppmu DT binding (Chanwoo Choi, Javier Martinez Canillas). - System sleep support updates (Alan Stern, Len Brown, SungEun Kim). - rockchip-io AVS support updates (Heiko Stuebner). - PM core clocks support fixup (Colin Ian King). - Power capping RAPL driver update including support for Skylake H/S and Broadwell-H (Radivoje Jovanovic, Seiichi Ikarashi). - Generic device properties framework fixes related to the handling of static (driver-provided) property sets (Andy Shevchenko). - turbostat and cpupower updates (Len Brown, Shilpasri G Bhat, Shreyas B Prabhu)" * tag 'pm+acpi-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (180 commits) cpufreq: speedstep-lib: Use monotonic clock cpufreq: powernv: Increase the verbosity of OCC console messages cpufreq: sfi: use kmemdup rather than duplicating its implementation cpufreq: drop !cpufreq_driver check from cpufreq_parse_governor() cpufreq: rename cpufreq_real_policy as cpufreq_user_policy cpufreq: remove redundant 'policy' field from user_policy cpufreq: remove redundant 'governor' field from user_policy cpufreq: update user_policy.* on success cpufreq: use memcpy() to copy policy cpufreq: remove redundant CPUFREQ_INCOMPATIBLE notifier event cpufreq: mediatek: Add MT8173 cpufreq driver dt-bindings: mediatek: Add MT8173 CPU DVFS clock bindings PM / Domains: Fix typo in description of genpd_dev_pm_detach() PM / Domains: Remove unusable governor dummies PM / Domains: Make pm_genpd_init() available to modules PM / domains: Align column headers and data in pm_genpd_summary output powercap / RAPL: disable the 2nd power limit properly tools: cpupower: Fix error when running cpupower monitor PM / OPP: Drop unlikely before IS_ERR(_OR_NULL) PM / OPP: Fix static checker warning (broken 64bit big endian systems) ...

Pull regulator updates from Mark Brown: "The biggest changes in the core this time around have been some refactorings that move us towards being able to drop the list of regulators maintained by the core and instead just use the driver model list maintained for the class devices for regulators which will make the code smaller and avoid some potential bugs.
