thinkpad-acpi: fix ALSA callback return status
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.
