sony-laptop: do not scribble keyboard backlight registers on resume

2013-11-26T04:03:36Z

Follow-up to commit 294d31e8227c ("sony-laptop: don't change keyboard backlight settings"): avoid messing up the state on resume. Leave it to what was before suspending as it's anyway likely that we still don't know what value we should write to the EC registers. This fix is also required in 3.12 Cc: stable@vger.kernel.org Tested-by: Karol Babioch Signed-off-by: Mattia Dongili Signed-off-by: Linus Torvalds

x86, wmi fix modalias_show return values

2013-11-21T01:16:22Z

I just fixed this same bug in arch/powerpc/kernel/vio.c and took a quick look for other similar errors in the kernel. modalias_show() should return an empty string on error, not errno. Signed-off-by: Prarit Bhargava Cc: Matthew Garrett Signed-off-by: Matthew Garrett

ipc: Added support for IPC interrupt mode

2013-11-21T01:16:21Z

This patch adds support for ipc command interrupt mode. Also added platform data option to select 'irq_mode' irq_mode = 1: configure the driver to receive IOC interrupt for each successful ipc_command. irq_mode = 0: makes driver use polling method to track the command completion status.

ipc: Enabled ipc support for additional intel platforms

2013-11-20T23:51:28Z

Enabled ipc support for penwell, clovertrail & tangier platforms. Signed-off-by: Kuppuswamy Sathyanarayanan Cc: David Cohen Signed-off-by: Matthew Garrett

ipc: Added platform data structure

2013-11-20T23:51:28Z

Since the same ipc driver can be used by many platforms, using macros for defining ipc_base and i2c_base addresses is not a scalable approach. So added a platform data structure to pass this information. Signed-off-by: Kuppuswamy Sathyanarayanan Acked-by: Alan Cox Cc: David Cohen Signed-off-by: Matthew Garrett

thinkpad_acpi: Fix build error when CONFIG_SND_MAX_CARDS > 32

2013-11-20T23:51:15Z

SNDRV_CARDS can be specified via Kconfig since 3.11 kernel, so this can be over 32bit integer range, which leads to a build error. Cc: [v3.11+] Signed-off-by: Takashi Iwai Signed-off-by: Matthew Garrett

platform: add chrome platform directory

2013-11-20T23:51:03Z

It makes sense to split out the Chromebook/Chromebox hardware platform drivers to a separate subdirectory, since some of it will be shared between ARM and x86. This moves over the existing chromeos_laptop driver without making any other changes, and adds appropriate Kconfig entries for the new directory. It also adds a MAINTAINERS entry for the new subdir.

hp-wmi: detect "2009 BIOS or later" flag by WMI 0x0d for wireless cmd

2013-11-20T23:51:03Z

Some HP BIOS has dummy WMI 0x05 cmd and it causes wireless set cmd to fail. This patch fixes the problem by detecting "2009 BIOS or later" flag which determines whether WMI 0x1b is supported and is used to replace WMI 0x05. Signed-off-by: Alex Hung Signed-off-by: Matthew Garrett
