2010-02-28asus-laptop: code movementCorentin Chary
The asus-laptop driver implements a number of interfaces like the backlight class driver.

2010-02-28asus-laptop: callbacks should use "driver data" parameter or fieldCorentin Chary
(Changelog stolen from Alan's patch for eeepc-laptop, but this patch does the same thing for asus-laptop) Callback methods should not refer to a variable like "asus" (formally "hotk"). Instead, they should extract the data they need either from a "driver data" parameter, or the "driver data" field of the object which they operate on. The "asus" variable can then be removed. In practice, drivers under "drivers/platform" can get away without using driver data, because it doesn't make sense to have more than one instance of them. However this makes it harder to review them for correctness. This is especially true for core ACPI developers who have not previously been exposed to this anti-pattern :-). This will serve as an example of best practice for new driver writers (whether they find it themselves, or have it pointed out during review :-). Signed-off-by: Corentin Chary <corentincj@iksaif.net>

2010-02-28asus-laptop: revise namesCorentin Chary

2010-02-28asus-laptop: add wireless and bluetooth status parameterCorentin Chary
These to parameter allow to set the status of wlan and bluetooth device when the module load. On some models, the device will always be down on boot, so the default behavior is to always enable these devices. Signed-off-by: Corentin Chary <corentincj@iksaif.net>
2010-02-28eeepc-laptop: check wireless hotplug eventsAlan Jenkins
Before we mark the wireless device as unplugged, check PCI config space to see whether the wireless device is really disabled (and vice versa). This works around newer models which don't want the hotplug code, where we end up disabling the wired network device. My old 701 still works correctly with this. I can also simulate an afflicted model by changing the hardcoded PCI bus/slot number in the driver, and it seems to work nicely (although it is a bit noisy). In future this type of hotplug support will be implemented by the PCI core. The existing blacklist and the new warning message will be removed at that point.

2010-02-27thinkpad-acpi: fix ALSA callback return statusHenrique de Moraes Holschuh
Clemens Ladisch reports that thinkpad-acpi improperly implements the ALSA API, and always returns 0 for success for the "put" callbacks while the API requires it to return "1" when the control value has been changed in the hardware/firmware. Rework the volume subdriver to be able to properly implement the ALSA API. Based on a patch by Clemens Ladisch <clemens@ladisch.de>. This fix is also needed on 2.6.33.

2010-02-25thinkpad-acpi: lock down video output state accessHenrique de Moraes Holschuh
Given the right combination of ThinkPad and X.org, just reading the video output control state is enough to hard-crash X.org. Until the day I somehow find out a model or BIOS cut date to not provide this feature to ThinkPads that can do video switching through X RandR, change permissions so that only processes with CAP_SYS_ADMIN can access any sort of video output control state. This bug could be considered a local DoS I suppose, as it allows any non-privledged local user to cause some versions of X.org to hard-crash some ThinkPads.

2010-02-25thinkpad-acpi: fix bluetooth/wwan resumeHenrique de Moraes Holschuh
Studying the DSDTs of various thinkpads, it looks like bit 3 of the argument to SBDC and SWAN is not "set radio to last state on resume". Rather, it seems to be "if this bit is set, enable radio on resume, otherwise disable it on resume". So, the proper way to prepare the radios for S3 suspend is: disable radio and clear bit 3 on the SBDC/SWAN call to to resume with radio disabled, and enable radio and set bit 3 on the SBDC/SWAN call to resume with the radio enabled. Also, for persistent devices, the rfkill core does not restore state, so we really need to get the firmware to do the right thing. We don't sync the radio state on suspend, instead we trust the BIOS to not do anything weird if we never touched the radio state since boot. Time will tell if that's a wise way of doing things...

2010-02-25thinkpad-acpi: make driver events work in NVRAM poll modeHenrique de Moraes Holschuh
Thadeu Lima de Souza Cascardo reports this: Brightness notification does not work until the user writes to hotkey_mask attribute. That's because the polling thread will only run if hotkey_user_mask is set and someone is reading the input device or if hotkey_driver_mask is set. In this second case, this condition is not tested after the mask is changed, because the brightness and volume drivers are started after the hotkey drivers. Fix tpacpi_hotkey_driver_mask_set() to call hotkey_poll_setup(), so that the poller kthread will be started when needed.

2010-02-25thinkpad-acpi: document HKEY event 3006Henrique de Moraes Holschuh
Event 0x3006 is used to help power management of the ODD in the UltraBay. The EC generates this event when the ODD eject button is pressed (even if the bay is powered down). Normally, Linux doesn't need this as we keep the SATA link powered up (which wastes power). The EC powers up the bay by itself when the ODD eject button is pressed, and the SATA PHY reports the hotplug. However, we could also power that SATA link down (and for that matter, also power down the Ultrabay) if the ODD is left idle for a while with no disk inside, and use event 0x3006 to know when we need that SATA link powered back up. For now, just stop asking for more information when event 0x3006 is seen, there is no point in pestering users about it anymore.
