The asus laptop driver conditionnaly registers leds in asus_led_register()
depending on their availability, but unconditionnaly unregisters them all at
exit time or when the module fails to load. Unregistering not registered leds
result in the following Oops. So we should check before unregistering.[] do_page_fault+0x511/0x5e9

Schedule /proc/acpi/event for removal in 6 months.
Re-name acpi_bus_generate_event() to acpi_bus_generate_proc_event()
to make sure there is no confusion that it is for /proc/acpi/event only.Add CONFIG_ACPI_PROC_EVENT to allow removal of /proc/acpi/event.

The previous events patch added a netlink event for every
user of the legacy /proc/acpi/event interface.However, some users of /proc/acpi/event are really input events,
and they already report their events via the input layer.Introduce a new interface, acpi_bus_generate_netlink_event(),
which is explicitly called by devices that want to repoprt
events via netlink. This allows the input-like events
to opt-out of generating netlink events. In summary:events that are sent via netlink:
ac/battery/sbs
thermal
processor
thinkpad_acpi dock/bayevents that are sent via input layer:
button
video hotkey
thinkpad_acpi hotkey
asus_acpi/asus-laptop hotkey

The current kconfig help text was misleading users. Also, the default for
an input-layer-optimized support caused way too many problems without
up-to-date userspace in place.So, rework the help text, and change the default to N. Note that
distributions are supposed to enable this option as soon as they update HAL
to a version that handles the thinkpad-acpi new input layer interface.Signed-off-by: Henrique de Moraes Holschuh

> Subject : drivers/misc/asus-laptop.c:*: error: 'struct led_classdev' has no member named 'class_dev'
> References : http://lkml.org/lkml/2007/7/22/299
> Submitter : Gabriel CFallout from f8a7c6fe14f556ca8eeddce258cb21392d0c3a2f. However, looking
at it shows that checks done in ASUS_LED_UNREGISTER() can't trigger
at all (we never get to asus_led_exit() if registration fails) and
if that registration fails, we actually leak stuff. IOW, it's worse
than just replacing class_dev with dev in there - the tests themselves
had been papering over the lousy cleanup logics.Signed-off-by: Al Viro

Recent Vaios (C, AR, N, FE) need some special initialization
sequence to enable Fn keys interrupts through the Embedded
Controller. Moreover Fn keys have to be decoded internally
using ACPI methods to get the key code.
Thus a new DMI table to add SNC init time callbacks and new
mappings for model-specific key code to generic sony-laptop
code have been added.Signed-off-by: Mattia Dongili

The backlight class does all the locking needed for sysfs access, but
offers no API to interface to that locking without an layer violation.Since we need to mutex-lock procfs access, implement in-driver locking for
brightness. It will go away the day thinkpad-acpi procfs goes away, or the
backlight class gives us a way to use its locks without a layer violation.Signed-off-by: Henrique de Moraes Holschuh

We get +128 instead of -128 from the DSDT TMPx methods, due to errors when
converting a EC byte return that is a s8 to an ACPI handler return that is
an int.Fix it once and for all, by clamping acceptable temperature readings from
DSDT TMPx so that anything outside the [-127,+127] range is converted to
TP_EC_THERMAL_TMP_NA (-128).Signed-off-by: Henrique de Moraes Holschuh

Lenovo ThinkPads have a slightly different key map layout from IBM
ThinkPads (fn+f2 and fn+f3 are swapped). Knowing which one we are dealing
with, we can properly set a few more hot keys up by default.Also, export the correct vendor in the input device, as that information
might be useful to userspace.Signed-off-by: Henrique de Moraes Holschuh

It appears that Lenovo decided to break the EC brightness control interface
in a weird way in their latest BIOSes. Fortunately, the old CMOS NVRAM
interface works just fine in such BIOSes.Add a module parameter that allows the user to select which strategy to use
for brightness control: EC, NVRAM, or both. By default, do both (which is
the way thinkpad-acpi used to work until now) on IBM ThinkPads, and use
NVRAM only on Lenovo ThinkPads.Signed-off-by: Henrique de Moraes Holschuh

Make the input layer the default way to deal with thinkpad-acpi hot keys,
but add a kernel config option to retain the old way of doing things.This means we map a lot more keys to useful stuff by default, and also that
we enable hot key handling by default on driver load (like Windows does).The documentation for proper use of this resource is also updated.

Add input device support to the hotkey subdriver.
Hot keys that have a valid keycode mapping are reported through the input
layer if the input device is open. Otherwise, they will be reported as
ACPI events, as they were before.Scan codes are reported (using EV_MSC MSC_SCAN events) along with EV_KEY
KEY_UNKNOWN events.For backwards compatibility purposes, hot keys that used to be reported
through ACPI events are not mapped to anything meaningful by default.
Userspace is supposed to remap them if it wants to use the input device for
hot key reporting.This patch is based on a patch by Richard Hughes .
