2015-06-19asus-laptop: Port to new backlight interface selection APIHans de Goede
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.

2015-01-28asus-laptop: use DEVICE_ATTR_xx macrosVivien Didelot
Use DEVICE_ATTR_{RO,WO,RW} macros to simplify sysfs attributes declaration. To declare a "foo" attribute, DEVICE_ATTR_RW() requires foo_show() and foo_store(), so rename a few functions to satisfy this requirement. Also put the macro below each related show/store functions for clarity. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: Darren Hart <dvhart@linux.intel.com>

2013-12-07ACPI: Clean up inclusions of ACPI header filesLv Zheng
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.

2013-01-07asus-laptop: Do not call HWRS on initBen Hutchings
Since commit 8871e99f89b7 ('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. Update the comment about HWRS in show_infos().

2013-01-03Drivers: platform: x86: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

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.

2011-10-24asus-laptop: Add rfkill support for Pegatron Lucid tabletAnisse Astier
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.

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.

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.
