acer-wmi: Add acpi_backlight=video quirk for the Acer KAV80

2014-11-13T18:03:06+00:00

commit 183fd8fcd7f8afb7ac5ec68f83194872f9fecc84 upstream.

The acpi-video backlight interface on the Acer KAV80 is broken, and worse
it causes the entire machine to slow down significantly after a suspend/resume.

Blacklist it, and use the acer-wmi backlight interface instead. Note that
the KAV80 is somewhat unique in that it is the only Acer model where we
fall back to acer-wmi after blacklisting, rather then using the native
(e.g. intel) backlight driver. This is done because there is no native
backlight interface on this model.

dell-wmi: Fix access out of memory

2014-10-17T07:43:22+00:00

commit a666b6ffbc9b6705a3ced704f52c3fe9ea8bf959 upstream.

Without this patch, dell-wmi is trying to access elements of dynamically
allocated array without checking the array size. This can lead to memory
corruption or a kernel panic. This patch adds the missing checks for
array size.

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

2013-12-04T19:05:41+00:00

commit b975dc3689fc6a3718ad288ce080924f9cb7e176 upstream.

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

thinkpad_acpi: Fix build error when CONFIG_SND_MAX_CARDS > 32

2013-11-29T19:27:54+00:00

commit cab6661344f14a09d7aecdf821a40f68ef9b18cc upstream.

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.

sony-laptop: don't change keyboard backlight settings

2013-10-22T11:31:46+00:00

Do not touch keyboard backlight unless explicitly passed a module
parameter.  In this way we won't make wrong assumptions about what are
good default values since they actually are different from model to
model.

The only side effect is that we won't know what is the current value
until set via the sysfs attributes.

platform: convert apple-gmux driver to dev_pm_ops from legacy pm_ops

2013-09-11T22:58:16+00:00

Convert drivers/platform/x86/apple-gmux to use dev_pm_ops instead of
legacy pm_ops.  This patch depends on pnp driver bus ops change to invoke
pnp_driver dev_pm_ops.
