It would appear that in BIOS's with nVidia hooks, the GUID
05901221-D566-11D1-B2F0-00A0C9062910 is duplicated. For now, the simplest
solution is to just ignore any duplicate GUIDs. These particular hooks are not
currently supported/ used in the kernel, so whoever does that can figure out
what the 'right' solution should be (if there's a better one).http://bugzilla.kernel.org/show_bug.cgi?id=14846

The commit 1fdd407f4e3f2ecb453954cbebb6c22491c61853 incorrectly made driver
abort loading when known GUID is present when it should have done exactly
the opposite.Signed-off-by: Dmitry Torokhov

When acpi_evaluate_object() is passed ACPI_ALLOCATE_BUFFER,
the caller must kfree the returned buffer if AE_OK is returned.The callers of wmi_get_event_data() pass ACPI_ALLOCATE_BUFFER,
and thus must check its return value before accessing
or kfree() on the buffer.Signed-off-by: Len Brown

Emphasize that that wmi_install_notify_handler() returns an acpi_status
rather than -errno by by testing ACPI_SUCCESS(), ACPI_FAILURE().No functional change in this patch, but this confusion caused a bug in dell-wmi.

backlight_device_register may return an ERR_PTR
value rather than a valid pointer.Problem found by Julia Lawall, properly fixed by Zhang Rui.

AML code always sends notifications to ACPI video device,
even if we disable the ACPI backlight control by using
boot option "acpi_backlight=vendor".In this case we should not print any warning message.

Today's -tip failed to build because commit
9e368fa011d4e0aa050db348d69514900520e40b ("ipmi: add PNP discovery (ACPI
namespace via PNPACPI)") from today's upstream kernel causes the following
build failure on x86, for CONFIG_ACPI=n && CONFIG_IPMI_SI=y:drivers/char/ipmi/ipmi_si_intf.c:3208: error: 'ipmi_pnp_driver' undeclared (first use in this function)
drivers/char/ipmi/ipmi_si_intf.c:3208: error: (Each undeclared identifier is reported only once
drivers/char/ipmi/ipmi_si_intf.c:3208: error: for each function it appears in.)
drivers/char/ipmi/ipmi_si_intf.c:3334: error: 'ipmi_pnp_driver' undeclared (first use in this function)The reason is that the ipmi_pnp_driver depends on ACPI facilities and is only
made available under ACPI - while the registration and unregistration is made
dependent on CONFIG_PNP:#ifdef CONFIG_PNP
pnp_register_driver(&ipmi_pnp_driver);
#endifThe solution is to only register this driver under ACPI. (Also, the CONFIG_PNP
dependency is not needed because pnp_register_driver() is stubbed out in the
!CONFIG_PNP case.)Signed-off-by: Ingo Molnar

Allow the user to choose through Kconfig if the Console Audio Control
interface (aka "volume subdriver") should be available or not.This not only saves some memory, but also allows the thinkpad-acpi
driver to be built-in even if ALSA is modular when the console audio
control interface is not wanted.This change fixes a build problem that is causing some annoyances, in
a way that doesn't disable the entire driver on kernels without ALSA
support.Signed-off-by: Henrique de Moraes Holschuh

If we cannot create the ALSA mixer, it is a good reason to fail to
load the volume subdriver, and not to fail to load the entire module.While at it, add more debugging messages, as the error paths are being
used a lot more than I'd expect, and it is failing to set up the ALSA
mixer on a number of ThinkPads.Reported-by: Peter Jordan

We don't want to be the first soundcard. We don't want to shift other
soundcards out of the way either, even if they load much later.Ask ALSA to (by default) load us in one of the last three slots. This
can be overriden at will using the "index" parameter.Reported-by: Whoopie

This fixes a "start_kernel(): bug: interrupts were enabled early".
rtc_cmos now takes care of initializing the ISA RTC and reading the
