commit 1915a718b1872edffcb13e5436a9f7302d3d36f0 upstream.
The return value of power_supply_register() call was not checked and
even on error probe() function returned 0. If registering failed then
during unbind the driver tried to unregister power supply which was not
actually registered.
This could lead to memory corruption because power_supply_unregister()
unconditionally cleans up given power supply.
Fix this by checking return status of power_supply_register() call. In
case of failure, clean up sysfs entries and fail the probe.

commit 4ec7a45b51a32ee513898e2f1e42bb681b340fcf upstream.
X550VB as many others Asus laptops need wapf4 quirk to make RFKILL
switch be functional. Otherwise system boots with wireless card
disabled and is only possible to enable it by suspend/resume.

commit 378008dfc72baed2d9c0f0a40dababc0e8901207 upstream.
The actual x401u does not use the so named x401u quirk but the x55u quirk.
All that the x401u quirk does it setting wapf to 4, so rename it to wapf4 to

commit c66263a368490a200a65639ff826f633090936a9 upstream.
BIOS won't light on the wifi-led after S3, so asus-wmi driver needs to
control the wifi and wifi-led status.
But, it'll lead to bt status error if asus-wmi driver controls bt as well.
So, for X200CA, asus-wmi driver controls wifi status only and have to set
wapf to 1.

commit 7939831eacd81fccbd7a956b30c7bb3abb9079db upstream.
We've observed the missing pvpanic call at panic, and it turned out
that this was blocked by the broken notifier of drm_fb_helper, where
scheduling may be called during switching to the fb console.
It's fairly difficult to fix the drm_fb problem and a quick fix isn't
foreseen, a simpler solution for the missing pvpanic call would be
just to call this earlier.
In order to assure that, this patch sets a higher priority to pvpanic
notifier_block. Once when the issue of drm_fb is resolved, we can
remove this priority again.

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 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.

The dev_attrs field of struct class is going away soon, dev_groups
should be used instead. This converts the wmi class code to use the
correct field.

It is somewhat strange that the default value to support the
depracated interface is set (1).
Anyway this has existed for years. The previous patch already
removed the functionality to still export events through /proc.
Now this param is useless and should vanish too.

It is quite some time that this one has been deprecated.
Get rid of it.
Should some really important user be overseen, it may be reverted and
the userspace program worked on first, but it is time to do something
to get rid of this old stuff...

Configuring this option as a module with ACPI_TOSHIBA built-in
results in the following errors:
drivers/built-in.o: In function `toshiba_acpi_remove':
>> toshiba_acpi.c:(.text+0x314bb0): undefined reference to `i8042_remove_filter'
drivers/built-in.o: In function `toshiba_acpi_add':

>> toshiba_acpi.c:(.devinit.text+0xb98b): undefined reference to `i8042_remove_filter'
Add a dependency to prevent ACPI_TOSHIBA from being built-in when
SERIO_I8042=m.

Intel Smart Connect is an Intel-specific ACPI interface for configuring
devices to wake up at regular intervals so they can pull down mail or other
internet updates, and then go to sleep again. If a user enables this in
Windows and then reboots into Linux, the device may wake up if it's put to
sleep. Since there's no Linux userland support for any of this, the machine
will then remain awake until something else puts it back to sleep.
I haven't figured out all that much about how this works (there's a bunch
of different ACPI calls available on the device), but this seems to be
enough to turn it off. We can add more features to this driver if anyone
ever cares about figuring out what the rest of the calls do or writing some
Linux userspace to implement the rest of it.
