Merge tag 'pinctrl-fixes-v3.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pinctrl fixes from Linus Walleij:

 - Three fixes to make the boot path for device tree work properly on
   the Nomadik pin controller.

 - Compile warning fix for the vt8500 driver.

 - Fix error path in pinctrl-single.

 - Free mappings in error path of the Lantiq controller.

 - Documentation fixes.
