2008-02-07leds: Standardise LED naming schemeRichard Purdie
As discussed on LKML some notion of 'function' is needed in LED naming. This patch adds this to the documentation and standardises existing LED drivers. Signed-off-by: Richard Purdie <rpurdie@rpsys.net>

2007-08-24asus-laptop: Fix rmmod of asus_laptopGuillaume Chazarain
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.

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. There is no functional change if CONFIG_ACPI_PROC_EVENT=y Signed-off-by: Len Brown <len.brown@intel.com>

2007-07-23ACPI: asus-laptop: Fix failure exitsAl Viro
> 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
Remove uneeded owner field from backlight_properties structure. Nothing uses it and it is unlikely that it will ever be used. The backlight class uses other means to ensure that nothing references unloaded code. Based on a patch from Dmitry Torokhov <dtor@insightbb.com> Signed-off-by: Richard Purdie <rpurdie@rpsys.net>

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/. If the user switchs the backlight using the keyboard, asus_hotk_notify looks for ATKD_LCD_OFF and ATKD_LCD_ON events, and stores the right state into hotk->status and bd->props->power .

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.

2007-01-30asus-laptop: add led supportCorentin Chary
Add led support, using generic led class. Thomas Tuttle's patch <http://lkml.org/lkml/2006/7/6/247> was very usefull. 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 ...

Adds the new driver and make ASUS_LAPTOP and ACPI_ASUS incompatible. It may be strange to use ASUS_CREATE_DEVICE_ATTR and ASUS_SET_DEVICE_ATTR now, but these macro will be very usefull in next patchs. ASUS_HANDLE and ASUS_HANDLE_INIT comes from IBM_HANDLE and IBM_HANDLE_INIT, with some modification, and will also be used in next patchs.
