2008-12-19create drivers/platform/x86/ from drivers/misc/Len Brown
Move x86 platform specific drivers from drivers/misc/ to a new home under drivers/platform/x86/. The community has been maintaining x86 vendor-specific platform specific drivers under /drivers/misc/ for a few years. The oldest ones started life under drivers/acpi. They moved out of drivers/acpi/ because they don't actually implement the ACPI specification, but either simply use ACPI, or implement vendor-specific ACPI extensions. In the future we anticipate... drivers/misc/ will go away. other architectures will create drivers/platform/<arch> Signed-off-by: Len Brown <len.brown@intel.com>

2008-10-11ACPI: Change acpi_evaluate_integer to support 64-bit on 32-bit kernelsMatthew Wilcox
As of version 2.0, ACPI can return 64-bit integers. The current acpi_evaluate_integer only supports 64-bit integers on 64-bit platforms. Change the argument to take a pointer to an acpi_integer so we support 64-bit integers on all platforms. lenb: replaced use of "acpi_integer" with "unsigned long long" lenb: fixed bug in acpi_thermal_trips_update() Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

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.

> 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 C <nix.or.die@googlemail.com> Fallout 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.

2007-07-11sysfs: kill unnecessary attribute->ownerTejun Heo
sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded. For more info regarding lifetime rule cleanup, please read the following message. http://article.gmane.org/gmane.linux.kernel/510293 (tweaked by Greg to not delete the field just yet, to make it easier to merge things properly.)

2007-02-20backlight: Separate backlight properties from backlight ops pointersRichard Purdie
Per device data such as brightness belongs to the indivdual device and should therefore be separate from the the backlight operation function pointers. This patch splits the two types of data and allows simplifcation of some code. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
2007-02-20backlight: Fix external uses of backlight internal semaphoreRichard Purdie
backlight_device->sem has a very specific use as documented in the header file. The external users of this are using it for a different reason, to serialise access to the update_status() method. backlight users were supposed to implement their own internal serialisation of update_status() if needed but everyone is doing things differently and incorrectly. Therefore add a global mutex to take care of serialisation for everyone, once and for all. Locking for get_brightness remains optional since most users don't need it. Also update the lcd class in a similar way. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
2007-02-20backlight: Remove unneeded owner fieldRichard Purdie

2007-01-30asus-laptop: add backlight supportCorentin Chary
Adds backlight support using backlight class. We now change the brightness *and toggle the backlight !* via /sys/class/backlight/asus-laptop/.

2007-01-30asus-laptop: add bluetooth and wlan supportCorentin Chary
WLED and BLED are not handled like other leds (MLED, etc ..), because sometime they also control the wlan/bluetooth device. If the method for wireless_status is found, it's used to get the status, otherwise hotk->status is used. We also use the HWRS method, which tell if the bluetooth/wlan device is present or not. This patch show why we need a ASUS_SET_DEVICE_ATTR macro : if there is a bluetooth device, /sys/dev.../asus-laptop/bluetooth is usable, else it's not but it's clean.

We use hotk->status to store led status because it's very hard to find acpi method to get the right status... To reduce the code, I use a lot of macro (ASUS_LED, ASUS_LED_REGISTER, etc ...), because the code is the same for all leds ...
