410c176519 msi-laptop: depends on RFKILL
msi-laptop uses rfkill*() interfaces so it should depend on RFKILL.

msi-laptop.c:(.text+0x1fcd1b): undefined reference to `rfkill_alloc'
msi-laptop.c:(.text+0x1fcd76): undefined reference to `rfkill_register'
msi-laptop.c:(.text+0x1fcdc8): undefined reference to `rfkill_destroy'
msi-laptop.c:(.text+0x1fcdd9): undefined reference to `rfkill_unregister'

This repairs "msi-laptop: Detect 3G device exists by standard ec command",
which is in some gregkh tree.

472ea12d1a msi-laptop: Support some MSI 3G netbook that is need load SCM
Some MSI 3G netbook only have one fn key to control Wlan/Bluetooth/3G,
those netbook will load the SCM (windows app) to disable the original
Wlan/Bluetooth control by BIOS when user press fn key, then control
Wlan/Bluetooth/3G by SCM (software control by OS). Without SCM, user
cann't on/off 3G module on those 3G netbook.
On Linux, msi-laptop driver will do the same thing to disable the
original BIOS control, then might need use HAL or other userland
application to do the software control that simulate with SCM.
e.g. MSI N034 netbook

ea79632d90 x86: move hp-wmi's probe function to .devinit.text
A pointer to hp_wmi_bios_setup is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

9129d14d29 asus-laptop: callbacks should use "driver data" parameter or field
(Changelog stolen from Alan's patch for eeepc-laptop, but this patch
does the same thing for asus-laptop)

Callback methods should not refer to a variable like "asus" (formally
"hotk").  Instead, they should extract the data they need either from
a "driver data" parameter, or the "driver data" field of the object
which they operate on.  The "asus" variable can then be removed.

In practice, drivers under "drivers/platform" can get away without using
driver data, because it doesn't make sense to have more than one
instance of them.  However this makes it harder to review them for
correctness.  This is especially true for core ACPI developers who have
not previously been exposed to this anti-pattern :-).

This will serve as an example of best practice for new driver writers
(whether they find it themselves, or have it pointed out during review
:-).

bc9d24a3ae eeepc-laptop: check wireless hotplug events
Before we mark the wireless device as unplugged, check PCI config space
to see whether the wireless device is really disabled (and vice versa).
This works around newer models which don't want the hotplug code, where
we end up disabling the wired network device.

My old 701 still works correctly with this.  I can also simulate an
afflicted model by changing the hardcoded PCI bus/slot number in the
driver, and it seems to work nicely (although it is a bit noisy).

In future this type of hotplug support will be implemented by the PCI
core.  The existing blacklist and the new warning message will be
removed at that point.

88cc83772a thinkpad-acpi: fix ALSA callback return status
Clemens Ladisch reports that thinkpad-acpi improperly implements the
ALSA API, and always returns 0 for success for the "put" callbacks
while the API requires it to return "1" when the control value has

Rework the volume subdriver to be able to properly implement the ALSA
API.  Based on a patch by Clemens Ladisch <clemens@ladisch.de>.

This fix is also needed on 2.6.33.

b525c06cdb thinkpad-acpi: lock down video output state access
Given the right combination of ThinkPad and X.org, just reading the
video output control state is enough to hard-crash X.org.

Until the day I somehow find out a model or BIOS cut date to not
provide this feature to ThinkPads that can do video switching through
X RandR, change permissions so that only processes with CAP_SYS_ADMIN
can access any sort of video output control state.

This bug could be considered a local DoS I suppose, as it allows any
non-privledged local user to cause some versions of X.org to
hard-crash some ThinkPads.

08fedfc903 thinkpad-acpi: fix bluetooth/wwan resume
Studying the DSDTs of various thinkpads, it looks like bit 3 of the
argument to SBDC and SWAN is not "set radio to last state on resume".
Rather, it seems to be "if this bit is set, enable radio on resume,
otherwise disable it on resume".

So, the proper way to prepare the radios for S3 suspend is: disable
radio and clear bit 3 on the SBDC/SWAN call to to resume with radio
disabled, and enable radio and set bit 3 on the SBDC/SWAN call to
resume with the radio enabled.

Also, for persistent devices, the rfkill core does not restore state,
so we really need to get the firmware to do the right thing.

We don't sync the radio state on suspend, instead we trust the BIOS to
not do anything weird if we never touched the radio state since boot.
Time will tell if that's a wise way of doing things...
