6f7e357bf1 platform/x86: asus-laptop: get rid of parse_arg()
parse_arg() duplicates the funcionality of kstrtoint() so use the latter
function instead. There is no funcionality change except that in the
case of input being too big -ERANGE will be returned instead of -EINVAL
which is not bad because -ERANGE makes more sense here. The check for
!count is already done by the sysfs core so no need to duplicate it
again. Also, add some minor corrections to error handling to accommodate
the change in return values (parse_arg returned count if everything
succeeded whereas kstrtoint returns 0 in the same situation)

As a result of this patch asus-laptop.ko size is reduced by almost 1%:

198b618ab1 asus-laptop: correct error handling in asus_read_brightness()
It is possible that acpi_evaluate_integer might fail and value would not be
set to any value so correct this defect by returning 0 in case of an
error. This is also the correct thing to return because the backlight
subsystem will print the old value of brightness in this case.

97ade7697b asus-laptop: Add key found on Asus F3M
Asus F3M has two keys labeled with an icon of a touchpad. The first,
reported as 0x6B is next to the power key and the second, reported as
0x6A, is F9 combined with Fn button. When I was pressing the latter, I was
getting "Unknown key 6a pressed" message before applying this patch.

Asus F3M does not support WMI so the commit does not update key mappings
in the asus-nb-wmi.c file.

I have not tested this mapping on any other Asus laptop.

8b9e6b70a1 asus-laptop: Port to new backlight interface selection API
Port the backlight selection logic to the new backlight interface
selection API.

This commit also removes various obsolete pr_xxx messages related to
backlight interface selection. These are obsolete because they assume
there is only a vendor or acpi backlight driver and no other choice.
Also they are not necessary, if the user wants to know which backlight
interfaces are registered a simple "ls /sys/class/backlight" suffices.

8b48463f89 ACPI: Clean up inclusions of ACPI header files
Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and
<acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h>
inclusions and remove some inclusions of those files that aren't
necessary.

First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>
should not be included directly from any files that are built for
CONFIG_ACPI unset, because that generally leads to build warnings about
undefined symbols in !CONFIG_ACPI builds.  For CONFIG_ACPI set,
<linux/acpi.h> includes those files and for CONFIG_ACPI unset it
provides stub ACPI symbols to be used in that case.

Second, there are ordering dependencies between those files that always
have to be met.  Namely, it is required that <acpi/acpi_bus.h> be included
prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the
latter depends on are always there.  And <acpi/acpi.h> which provides
basic ACPICA type declarations should always be included prior to any other
ACPI headers in CONFIG_ACPI builds.  That also is taken care of including
<linux/acpi.h> as appropriate.

Since commit 8871e99f89 ('asus-laptop: HRWS/HWRS typo'), module
initialisation is very slow on the Asus UL30A.  The HWRS method takes
about 12 seconds to run, and subsequent initialisation also seems to
be delayed.  Since we don't really need the result, don't bother
calling it on init.  Those who are curious can still get the result
through the 'infos' device attribute.

774b06780b asus-laptop: control how BLED and WLED should be exposed
Let the user tells if BLED and WLED should be exposed as led or
rfkill (the old sysfs are still here, but this adds a standard
interface to control the device).

For example on my A6JC, with WAPF=1, I would do:

$ modprobe asus-laptop wled_type=led bluetooth_type=rfkill

There is still no known way to automatically guess what BLED
and WLED methods will control, it's why user information is needed.

A userspace database could do that automatically, and maybe some DMI
matching in the driver.

149083996e asus-laptop: Add rfkill support for Pegatron Lucid tablet
Add three new rfkill switches in this driver that are specific to
Pegatron Lucid tablet.
Please note that you might not need all three switches. For example if
you don't have a 3G module inside your tablet.

Also, on my device, the gpio for the wifi/bt module is connected to the
bluetooth line. Therefore to activate your wireless lan interface, you
need to use the "pega-bt" rfkill switch.

Finally, the rfkill switch only works before the wireless module is
loaded the first time. Unloading ath9k doesn't help, a reboot is
necessary.

8fcf71aa00 platform-drivers-x86: asus-laptop: fix wrong test for successful registered led_classdev
device_create returns &struct device pointer on success, or ERR_PTR() on error.
Thus if led_classdev_register fails, led_cdev->dev is always not NULL.

Thus to unregister a successful registered led_classdev, we should check
IS_ERR_OR_NULL macro for led_cdev->dev instead of checking if led_cdev->dev
is NULL or not.

we use IS_ERR_OR_NULL instead of IS_ERR because if we havn't call
led_classdev_register, the led_cdev->dev is NULL.

3b81cf9d55 asus-laptop: remove deprecated interfaces (lcd_switch and display_get)
I should have done that one year ago, so it's more than
time to do it.

These two features use non-standard interfaces. There are the
only features that really need multiple path to guess what's
the right method name on a specific laptop.

Removing them allow to remove a lot of code an significantly
clean the driver.

This will affect the backlight code which won't be able to know
if the backlight is on or off.

The platform display file will also be write only (like the one
in eeepc-laptop).
