For now, I fixed it the easiest and most obvious way: Check if the result is sane and if it isn't use a sane default instead.

2011-10-24acer-wmi: add ACER_WMID_v2 interface flag to represent new notebooksLee, Chun-Yi1-203/+213
There have new acer notebooks' BIOS provide new WMID_GUID3 and ACERWMID_EVENT_GUID methods. Some of machines still keep the old WMID_GUID1 method but more and more machines were already removed old wmi methods from DSDT. So, this patch add a new ACER_WMID_v2 interface flag to represent new acer notebooks, the following is definition: + ACER_WMID: It means this machine only provides WMID_GUID1/2 methods. + ACER_WMID_v2: It means this machine provide new WMID_GUID3 and WMID_EVENT_GUID methods. Some ACER_WMID_v2 machines also provide old WMID_GUID1/2 methods, but we still query/set communication device's state by new WMID_GUID3 method.

2011-10-24asus-laptop: Add rfkill support for Pegatron Lucid tabletAnisse Astier1-0/+103
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.

2011-10-24Platform: Detect samsung laptop quirk when initial level is zeroJohn Serock1-2/+8
This patch depends on the "Platform: Brightness quirk for samsung laptop driver" patch from Jason Stubbs. This patch adds a check for an initial brightness level of 0; if the level is 0, this patch changes the brightness level to 1 before the driver attempts to detect the brightness quirk. The Samsung N150 netbook experiences the brightness quirk. Without Jason's patch, the only brightness levels available on the N150 are 0, 1, and 8. This patch ensures that, when the initial brightness level is 0, the samsang-laptop driver detects the brightness quirk on the N150, thereby making brightness levels 0 through 8 available.

2011-10-24topstar-latop: ignore 0x82 eventManuel Lauss1-0/+1
Event 0x82 is emitted whenever a backlight event happens (brightness change, backlight on/off). For instance, when display is switched off after a timeout, event 0x82 is emitted, and along with it a keypress which switches the display back on again. This patch adds 0x82 to the event ignore list so that the display stays off when it is automatically switched off.

Test for features up-front to determine whether or not they are supported, and avoid creating devices and proc files for unsupported features. Signed-off-by: Seth Forshee <seth.forshee@canonical.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>
2011-10-24toshiba_acpi: Support SPFC as an HCI methodSeth Forshee1-6/+22
Some Toshiba models, notably those with the TOS1900 device, use the SPFC method for HCI calls instead of GHCI. Test for this method if GHCI isn't found, and if it exists use it for all HCI calls.

2011-10-24toshiba_acpi: Use handle for HCI callsSeth Forshee1-40/+15
Now that we're using an acpi driver we already have a handle to the namespace of the HCI call, so there's no need to test various paths to the HCI call or even be aware of the path at all.

2011-10-24toshiba_acpi: Convert to use acpi_driverSeth Forshee1-245/+261
Changes toshiba_acpi to register an acpi driver and eliminates the platform device it was using. Also eliminates most global variables, moving them into toshiba_acpi_dev, along with some other miscellaneous fixes and cleanup.

2011-10-24Platform: Brightness quirk for samsung laptop driverJason Stubbs1-0/+43
On some Samsung laptops the brightness regulation works slightly different. All SABI commands except for set_brightness work as expected. The behaviour of set_brightness is as follows: - Setting a new brightness will only step one level toward the new brightness level. For example, setting a level of 5 when the current level is 2 will result in a brightness level of 3. - A spurious KEY_BRIGHTNESS_UP or KEY_BRIGHTNESS_DOWN event is also generated along with the change in brightness. - Neither of the above two issues occur when changing from/to brightness level 0. This patch adds detection and a non-intrusive workaround for the above issues.

2011-10-24platform: samsung_laptop: fix samsung brightness min/max calculationsJason Stubbs1-3/+6
The min_brightness value of the sabi_config is incorrectly used in brightness calculations. For the config where min_brightness = 1 and max_brightness = 8, the user visible range should be 0 to 7 with hardware being set in the range of 1 to 8. What is actually happening is that the user visible range is 0 to 8 with hardware being set in the range of -1 to 7. This patch fixes the above issue as well as a miscalculation that would occur in the case of min_brightness > 1.
