toshiba_acpi: fix and cleanup toshiba_kbd_bl_mode_store()

2014-09-03T17:45:12+00:00

The current code just returns -EINVAL because mode can't be equal to both 1 and 2. Also this function is messy so I have cleaned it up: 1) Remove initializers like "int time = -1". Initializing variables to garbage values turns off GCC's uninitialized variable warnings so it can lead to bugs. 2) Use kstrtoint() instead of sscanf(). 3) Use SCI_KBD_MODE_FNZ and SCI_KBD_MODE_AUTO instead of magic numbers 1 and 2. 4) Don't check for "mode == -1" because that can't happen. 5) Preserve the error code from toshiba_kbd_illum_status_set().

platform/x86: toshiba: re-enable acpi hotkeys after suspend to disk

2014-09-02T22:45:36+00:00

On the Toshiba Tecra Z40, after a suspend-to-disk, some FN hotkeys driven by toshiba_acpi are not functional. Calling the ACPI object ENAB on resume makes them back alive. Signed-off-by: Benjamin Tissoires Acked-by: Matthew Garrett Signed-off-by: Darren Hart

ideapad-laptop: Constify DMI table for real!

2014-09-02T22:16:24+00:00

This is a follow-up patch to commit 49458e83082d ("ideapad-laptop: Constify DMI table and other r/o variables") to do what its commit message says. The actual commit differs from the patch posted at https://www.mail-archive.com/platform-driver-x86@vger.kernel.org/msg05340.html significantly, probably due to a bad merge conflict resolution. Fix up the mess and constify the DMI table for real and fix the bogus double-const of ideapad_rfk_data[].

Revert "ideapad-laptop: Disable touchpad interface on Yoga models"

2014-08-28T07:57:07+00:00

I've received a bug report from a user that the touchpad control part of the ideapad-laptop ACPI interface does work for him on his "Lenovo Yoga 2 13", and that this patch causes a regression for him. Since it did not work for me when I had a "Lenovo Yoga 2 11" in my own hands (loaned from a friend). It seems that this is a bit of hit and miss. Since the result of having a false positive here is worse, then the minor annoyance of a false touchpad disabled messages being shown after suspend / resume on models (or is it firmware versions?) where the interface does not work, simply revert the patch. This reverts commit f79a901331a823ae370584b15cd39dd110b95a0a. Reported-by: GOESSEL Guillaume Signed-off-by: Hans de Goede Signed-off-by: Darren Hart

platform/x86: Toshiba HDD Active Protection Sensor

2014-08-16T08:23:56+00:00

This driver adds support for the built-in accelereometer found on recent Toshiba laptops with HID TOS620A. This driver receives ACPI notify events 0x80 when the sensor detects a sudden move or a harsh vibration, as well as an ACPI notify event 0x81 whenever the movement or vibration has been stabilized. Also provides sysfs entries to get/set the desired protection level and reseting the HDD protection interface. Signed-off-by: Azael Avalos Signed-off-by: Matthew Garrett
