dell-wmi: Fix access out of memory

2014-11-21T17:22:55+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.

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

2014-11-14T16:48:01+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.

drivers/platform/olpc/olpc-ec.c: initialise earlier

2013-08-29T16:47:38+00:00

commit 93dbc1b3b506e16c1f6d5b5dcfe756a85cb1dc58 upstream.

Being a low-level component, various drivers (e.g.  olpc-battery) assume
that it is ok to communicate with the OLPC Embedded Controller during
probe.  Therefore the OLPC EC driver must be initialised before other
drivers try to use it.  This was the case until it was recently moved
out of arch/x86 and restructured around commits ac2504151f5a ("Platform:
OLPC: turn EC driver into a platform_driver") and 85f90cf6ca56 ("x86:
OLPC: switch over to using new EC driver on x86").

Use arch_initcall so that olpc-ec is readied earlier, matching the
previous behaviour.

Fixes a regression introduced in Linux-3.6 where various drivers such as
olpc-battery and olpc-xo1-sci failed to load due to an inability to
communicate with the EC.  The user-visible effect was a lack of battery
monitoring, missing ebook/lid switch input devices, etc.

Add support for fan button on Ideapad Z580

2013-05-09T00:00:50+00:00

The patch adds support for fan control button on Ideapad Z580. This is
the same button as on Z570, but it raises different bit in
VPCCMD_R_SPECIAL_BUTTONS. Also add message to dmesg when unknown button
press detected, it will help adding support for new special buttons.
