2012-07-01ACPI / PM: Drop pm_message_t argument from device suspend callbackRafael J. Wysocki
None of the drivers implementing the ACPI device suspend callback uses the pm_message_t argument of it, so this argument may be dropped entirely from that callback. This will simplify switching the ACPI bus type to PM handling based on struct dev_pm_ops. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2012-06-26intel_ips: blacklist HP ProBook laptopsTakashi Iwai
intel_ips driver spews the warning message "ME failed to update for more than 1s, likely hung" at each second endlessly on HP ProBook laptops with IronLake.

2012-06-26ideapad: uninitialized data in ideapad_acpi_add()Dan Carpenter
We only initialize the high bits of "cfg". It probably doesn't cause a problem given that this is platform specific code and doesn't have to worry about endianness etc. But it's sort of messy. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>

2012-06-26sony-laptop: fix sony_nc_sysfs_store()Dan Carpenter
We made this an unsigned long and it causes a bug on 64 bit big endian systems when we try to pass the value to sony_nc_int_call().

2012-06-01apple-gmux: Fix up the suspend/resume patchMatthew Garrett
I incorporated the wrong version of the suspend/resume patch for gmux, and so lost David Woodhouse's fix to leave the backlight level unchanged over suspend/resume. This fixes it up to v2. Signed-off-by: Matthew Garrett <mjg@redhat.com>
2012-06-01dell-laptop: Remove rfkill codeMatthew Garrett
The interface just doesn't work on some machines, and Dell haven't been able to tell us either which machines those are or what we should be doing instead. This would be fine, except it results in userspace ending up confused and general sadness. So let's just rip it out for now. Signed-off-by: Matthew Garrett <mjg@redhat.com>

A few models offer the chance to set whether to resume from S3 and/or S4 when opening the lid. [malattia@linux.it: create three sysfs files for S3/4/5 rather than using a single one accepting a bitmask. Support S5 since the DSDT exports it.

2012-05-31sony-laptop: improve SNC initialization and acpi notify callback codeMarco Chiappero
Loop through the list of SNC handles and run the proper initialization function for each of the known handles. Also return void in function where we are not checking the return value anyway. For notifications we also know which handle is linked to the event and the code becomes simpler to read with a switch rather than using convoluted ifs. [malattia@linux.it: Code reworked to merge the initialization code improvements and the notify callback changes. Modified the code paths to allow easier error exit paths. Also fixed some missing break statements and spelling mistakes.] Signed-off-by: Marco Chiappero <marco@absence.it> Signed-off-by: Mattia Dongili <malattia@linux.it> Signed-off-by: Matthew Garrett <mjg@redhat.com>
2012-05-31sony-laptop: use kstrtoul to parse sysfs valuesMattia Dongili

2012-05-31sony-laptop: generalise ACPI calls into SNC functionsMattia Dongili
All calls into the SNC device methods have zero or one arguments and return an integer or a buffer (some functions go as far as returning an integer _or_ a buffer depending on the input parameter...). This allows simplifying a couple of code paths and prepares the field for other users of functions returning buffers.

2012-05-31sony-laptop: use soft rfkill status stored in hwMarco Chiappero
The SNC device on recent Vaio laptops also stores the soft status and leaves it available after reboot. Use it and always set the last soft and hard status on module load.

2012-05-31toshiba_acpi: Add support for transflective LCDAkio Idehara
Some Toshiba laptops have the transflective LCD and toshset can control its backlight state. I brought this feature to the mainline. To support transflective LCD, it's implemented by adding an extra level to the backlight and having 0 change to transflective mode. It was tested on a Toshiba Portege R500.

2012-05-31toshiba_acpi: Only register backlight device when interface is read/writeSeth Forshee
Currently the backlight device is registered unconditionally, but many (probably most) Toshibas either don't support HCI_LCD_BRIGHTNESS or only support reading from it. This patch adds a test of HCI_LCD_BRIGHTNESS during initialization and only registers the backlight device if this interface supports both reads and writes.

2012-05-31thinkpad-acpi: fix issuing duplicated key events for brightness up/downAlex Hung
The tp_features.bright_acpimode will not be set correctly for brightness control because ACPI_VIDEO_HID will not be located in ACPI. As a result, a duplicated key event will always be sent. acpi_video_backlight_support() is sufficient to detect standard ACPI brightness control.

2012-05-31apple-gmux: Add suspend/resume support for the backlightSeth Forshee
After S3, the brightness might not be restored to the pre-suspend value. Request status update calls from the backlight core on suspend/resume to ensure the brightness value is restored.

2012-05-31xo1-rfkill: only act when blocked state is changedDaniel Drake
The XO-1 rfkill driver should only send EC commands when changing between blocked/unblocked state. The rfkill switch is asked to be unblocked on every resume (even when the card was never blocked before) and sending a EC_WLAN_LEAVE_RESET command here upsets the resume sequence of the libertas driver. Adding the check to avoid the spurious EC_WLAN_LEAVE_RESET fixes the wifi resume behaviour. The rfkill state is maintained by the hardware over suspend/resume so no extra consideration is needed here.
