dell-wmi: Fix access out of memory 2014-11-21T17:22:55+00:00 Pali Rohár pali.rohar@gmail.com 2014-09-29T13:10:51+00:00 2a7978ef959430e21d93a6ab59284a11bc2c9bb6 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.

acer-wmi: Add acpi_backlight=video quirk for the Acer KAV80 2014-11-14T16:48:01+00:00 Hans de Goede hdegoede@redhat.com 2014-10-22T14:06:38+00:00 018fd7f83f65eed43a6c655686e05c95bab03637 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.
