In function pinctrl_get_locked, pointer p is returned on
error, and also return on no_error.
So, we just return it with no error test.It's pretty the same in function pinctrl_lookup_state_locked:
state is returned in every case, so we drop the error test
and just return state.Signed-off-by: Richard Genoud

The irqdomain conversion failed to notice that we do not always

Pull pin control changes from Linus Walleij:
"These are the accumulated pin control patches for v3.6:
- Various cleanups to the U300 driver
- Refactor the pin control core to automatically remove any GPIO
ranges when the drivers are removed, instead of having the drivers
do this explicitly.
- Add a function for registering a batch of GPIO ranges.
- Fix a number of incorrect but non-regressive error checks.
- Incremental improvements to the COH901, i.MX and Nomadik drivers
- Add a one-register-per-pin entirely Device Tree-based pin control

Pull arm-soc device tree description updates from Arnd Bergmann:
"This branch contains two kinds of updates: Some platforms in the
process of getting converted to device tree based booting, and the
platform specific patches necessary for that are included here.Other platforms are already converted, so we just need to update the
actual device tree source files and the binding documents to add
support for new board and new drivers.In the future we will probably separate those into two branches, and
in the long run, the plan is to move the device tree source files out
of the kernel repository, but that has to wait until we have completed
a much larger portion of the binding documents."Fix up trivial conflicts in arch/arm/mach-imx/clk-imx6q.c due to newly

if a pin or some pins of a group has NO_PAD_CTL property, the map_num
and the grp->npin are different definitely.When we set mapping information to the new_map[], we should skip those
pins with NO_PAD_CTL from index, otherwise it is possible the driver
