ASoC: Use nested lock for snd_soc_dapm_mutex_lock

2015-12-30T16:48:13Z

snd_soc_dapm_mutex_lock currently uses the un-nested call which can cause lockdep warnings when called from control handlers (a relatively common usage) and using modules. As creating the control causes a potential mutex inversion with the handler, creating the control will take the controls_rwsem under the dapm_mutex and accessing the control will take the dapm_mutex under controls_rwsem. All the users look like they want to be using the runtime class of the lock anyway, so this patch just changes snd_soc_dapm_mutex_lock to use the nested call, with the SND_SOC_DAPM_CLASS_RUNTIME class.

ALSA: hda - Fix playback noise with 24/32 bit sample size on BXT

2015-12-07T08:04:44Z

In BXT-P A0, HD-Audio DMA requests is later than expected, and makes an audio stream sensitive to system latencies when 24/32 bits are playing. Adjusting threshold of DMA fifo to force the DMA request sooner to improve latency tolerance at the expense of power. v2: move Intel specific code to hda_intel.c Signed-off-by: Lu, Han Signed-off-by: Takashi Iwai

ASoC: dapm: Reset dapm wcache after freeing damp widgets

2015-11-10T18:52:06Z

If there is anything in damp->path_source_cache or damp->path_sink_cache, it can not be valid after the widgets have been freed. Without this patch a repeated remove and load of a machine driver may cause NULL pointer reference in dapm_wcache_lookup() when a freed widget, not belonging to any list, is haunting in the wcache.

ALSA: Constify ratden/ratnum constraints

2015-10-28T10:42:22Z

The ALSA core does not modify the constraints provided by a driver. Most constraint helper functions already take a const pointer to the constraint description, the exception at the moment being the ratden and ratnum constraints. Make those const as well, this allows a driver to declare them as const. Signed-off-by: Lars-Peter Clausen Signed-off-by: Takashi Iwai

ASoC: Updates for v4.4 Not much core work here, a few small tweaks to interfaces but mainly the changes here are driver ones. Highlights include: - Updates to the topology userspace interface - Big updates to the Renesas support from Morimoto-san - Most of the support for Intel Sky Lake systems. - New drivers for Asahi Kasei Microdevices AK4613, Allwinnner A10, Cirrus Logic WM8998, Dialog DA7219, Nuvoton NAU8825 and Rockchip S/PDIF. - A new driver for the Atmel Class D speaker drivers
