Calling the ENAB method on Toshiba laptops results in notifications being
sent when laptop hotkeys are pressed. This patch simply calls that method
and sets up an input device if it's successful.Signed-off-by: Matthew Garrett

Instead of a MODULE_DEVICE_TABLE for every acpi_driver ids table, we
create a table containing all ids to export to get a module alias for
each one.This will fix automatic loading of the driver when one of the ACPI
devices is not present (like the accelerometer, which is not present in
some models).Signed-off-by: Thadeu Lima de Souza Cascardo
-
Right now, we assume that the hardware rfkill switch on Dells toggles all
radio devices. In fact, this can be configured in the BIOS and so right
now we may mark a device as hardware killed even when it isn't. Add code
to query the devices controlled by the switch, and use this when
determining the hardware kill state of a radio.Signed-off-by: Matthew Garrett

Calls to communicate with system firmware via a SMI (using dcdbas)
need to use a buffer that has a physical address of 4GB or less.
Currently the dell-laptop driver does not guarantee this, and when the
buffer address is higher than 4GB, the address is truncated to 32 bits
and the SMI handler writes to the wrong memory address.Signed-off-by: Stuart Hayes

The "hardware" switch is tied directly to a BIOS interface that will
connect and disconnect the hardware from the bus.If you use the software interface to request the BIOS to make these
changes, the HW switch will be in an inconsistent state and LEDs may not
reflect the state of the HW.Signed-off-by: Mario Limonciello

The rfkill interface on Dells only sends a notification that the switch
has been changed via the keyboard controller. Add a filter so we can
pick these notifications up and update the rfkill state appropriately.Signed-off-by: Matthew Garrett

This drops the support for manually groking the files in sysfs

of platform rfkill support.It has been combined into a single patch to not introduce regressions

The EeePC 4G ("701") implements CFVS, but it is not supported by the
pre-installed OS, and the original option to change it in the BIOS
setup screen was removed in later versions. Judging by the lack of
"Super Hybrid Engine" on Asus product pages, this applies to all "701"
models (4G/4G Surf/2G Surf).So Asus made a deliberate decision not to support it on this model.
We have several reports that using it can cause the system to hang [1].
That said, it does not happen all the time. Some users do not
experience it at all (and apparently wish to continue "right-clocking").Check for the EeePC 701 using DMI. If met, then disable writes to the
"cpufv" sysfs attribute and log an explanatory message.Add a "cpufv_disabled" attribute which allow users to override this
policy. Writing to this attribute will log a second message.The sysfs attribute is more useful than a module option, because it
makes it easier for userspace scripts to provide consistent behaviour
(according to user configuration), regardless of whether the kernel
includes this change.[1]

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

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

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
