regulator: gpio-regulator: Don't oops on missing regulator-type property

Catch missing regulator-type property in DT and return an error
gracefully instead of deferencing a NULL pointer and crashing.

regulator: fixed: fix regulator_list_voltage() for regression

Commit c368e5fc2a190923b786f2de3e79430ea3566a25 "regulator: fixed:
get rid of {get|list}_voltage()" broke regulator_list_voltage() for
the fixed regulator, because an earlier commit
5a523605afa7d3b54b2e7041f8c9e6bc39872a7e "regulator: core: provide
fixed voltage in desc for single voltage rail" missed to add support
for the fixed-voltage special case to that function. This patch
fixes that regression.

regulator: pfuze100: allow misprogrammed ID

prior to week 08 of 2013 Freescale misprogrammed between 1 and 3% of
PFUZE1000 parts with a ID=0x8 instead of the expected ID=0x0

regulator: arizona-micsupp: Correct wm5110 voltage selection

wm5110 provides different voltage configurations than the other Arizona
parts, this patch adds support for this into the regulator driver. Also
fixup the default for the configuration register for wm5110.

 "A bunch of fixes, a few driver specific ones and a framework fix for
  voltage enumeration on fixed voltage regulators which had previously
  worked but had been misplaced during some refactoring causing problems
  for users that needed to know the voltage"

sony-laptop: do not scribble keyboard backlight registers on resume

Follow-up to commit 294d31e8227c ("sony-laptop: don't change keyboard
backlight settings"): avoid messing up the state on resume.  Leave it to
what was before suspending as it's anyway likely that we still don't
know what value we should write to the EC registers.  This fix is also
required in 3.12
