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

2015-02-02T09:05:10+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.

thinkpad-acpi: fix issuing duplicated key events for brightness up/down

2014-06-07T23:02:07+00:00

commit ff413195e830541afeae469fc866ecd0319abd7e upstream.

The tp_features.bright_acpimode will not be set correctly for brightness
control because ACPI_VIDEO_HID will not be located in ACPI. As a result,
a duplicated key event will always be sent. acpi_video_backlight_support()
is sufficient to detect standard ACPI brightness control.

thinkpad-acpi: recognize latest V-Series using DMI_BIOS_VENDOR

2013-06-07T19:49:49+00:00

commit a4f46bb9fa84642e356898ee44b670989622f8bb upstream.

In the latest V-series bios DMI_PRODUCT_VERSION does not contain
the string Lenovo or Thinkpad, but is set to the model number, this
causes the thinkpad_acpi module to fail to load. Recognize laptop
as Lenovo using DMI_BIOS_VENDOR instead, which is set to Lenovo.

hp_accel: Ignore the error from lis3lv02d_poweron() at resume

2013-05-19T17:54:38+00:00

commit 7783819920ca52fc582a2782f654fe6ed373f465 upstream.

The error in lis3lv02_poweron() is harmless in the resume path, so
we should ignore it. It is inline with the other usages of lis3lv02_poweron()
and matches the 3.0 code for this routine. This patch is in suse git and
might have missed making it into the mainline.

asus-laptop: Do not call HWRS on init

2013-03-28T19:12:28+00:00

commit cb7da022450cdaaebd33078b6b32fb7dd2aaf6db upstream.

Since commit 8871e99f89b7 ('asus-laptop: HRWS/HWRS typo'), module
initialisation is very slow on the Asus UL30A.  The HWRS method takes
about 12 seconds to run, and subsequent initialisation also seems to
be delayed.  Since we don't really need the result, don't bother
calling it on init.  Those who are curious can still get the result
through the 'infos' device attribute.

Update the comment about HWRS in show_infos().

samsung-laptop: Disable on EFI hardware

2013-02-14T18:48:54+00:00

commit e0094244e41c4d0c7ad69920681972fc45d8ce34 upstream.

It has been reported that running this driver on some Samsung laptops
with EFI can cause those machines to become bricked as detailed in the
following report,

	https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557

There have also been reports of this driver causing Machine Check
Exceptions on recent EFI-enabled Samsung laptops,

	https://bugzilla.kernel.org/show_bug.cgi?id=47121

So disable it if booting from EFI since this driver relies on
grovelling around in the BIOS memory map which isn't going to work.
