The alternative of CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME may be replaced with CONFIG_PM too. Make these changes in 2 files under drivers/video/. Signed-off-by: Rafael J.

As a result, we will not create a backlight device for it while we should. Solve this problem by special case the firmware that has 8+ output devices in that if we see such a firmware, we do not test if the device is in _DOD list. The creation of the backlight device will also enable the firmware to emit events on backlight hotkey press when the acpi_osi= cmdline option is specified on those affected ASUS laptops.

It calls acpi_disable_gpe() on a GPE that's not enabled and this causes ACPICA to return the AE_LIMIT status code from that call which then is reported as an error by the ACPICA's debug facilities (if enabled). This may lead to a fair amount of confusion, so introduce a new ACPI device wakeup flag to store the wakeup GPE status and avoid disabling wakeup GPEs that have not been enabled.

Drop the kernel messages from there entirely and leave the acpi_util_eval_error() to handle the debug printing. In one case, replace the kernel message with a call to acpi_util_eval_error().

(These are separate from the standard mixer.) By default, the buttons are: - Mute: Mutes the hardware volume control and, on some models, generates KEY_MUTE. - Up: Unmutes, generates KEY_VOLUMEUP, and increases volume if applicable. (Newer thinkpads only have hardware mute/unmute.) - Down: Unmutes, generates KEY_VOLUMEDOWN, and decreases volume if applicable. This behavior is unfortunate, since modern userspace will also handle the hotkeys and change the other mixer. If the software mixer is muted and the hardware mixer is unmuted and you push mute, hilarity ensues as they both switch state. Rather than adding a lot of complex ALSA integration to fix this, just disable the special ThinkPad volume controls when possible. This turns the mute and volume buttons into regular buttons, and standard software controls will work as expected. ALSA already knows about the mute light on models with a mute light, so everything should just work. This should also allow us to remove _OSI(Linux) for all ThinkPads. For future reference: It turns out that we can ask ACPI for one of three behaviors directly on very new models. They are "latch" (the default), "none" (no automatic control), and "toggle" (mute unmutes when muted). All of the modes besides "none" seem to be a bit buggy, though, and there doesn't seem to be a consistent way to get any notification when the HW mute state is changed.

| * | | | | | | | | | | | | dell-wmi: Update code for processing WMI eventsPali Rohár2014-11-191-31/+128

First value in buffer is length of event followed by data of specified length. After that is next length and next data. When length is zero then there is no more events in bufffer. This patch adds support for processing all events in buffer (not only first) and parse more event types (not only hotkey events). Because of variable length of events sometimes BIOS fills more hotkeys (or other values) into single WMI event. In this case this patch also processes these multiple hotkeys (and not only first one). Some event types are just ignored because kernel is not interested in them (e.g. NIC Link status, battery unplug, ...). This patch is based on DSDT table from Dell Latitude E6440. Code should be backward compatible so will process other events of old types same as before this patch. This patch also fixes a problem with unknown WMI event messages being written to the log. Now all known events are parsed and those which are not interesting to the kernel are dropped without an unknown WMI event message.

However, it is possible that get_acpi() returns an error instead. We should not be writing error values to the ACPI device, even though it's quite possible that we couldn't contact the ACPI device in the first place.
