Merge tag 'pinctrl-fixes-v3.7-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pinctrl fixes from Linus Walleij:
 "A number of pinctrl fixes for the v3.7 series:
   - duplicate includes, section markup, code mishaps
   - erroneous return value in errorpath on the bcm2835 driver
   - remove an unused sirf function that was causing build errors
   - multiple-platform compilation stubs and a missed code review
     comment fixup on the nomadik pin controller"

* tag 'pinctrl-fixes-v3.7-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:
  pinctrl/nomadik: always use the simple irqdomain
  pinctrl/nomadik: provide stubs for legacy Nomadik
  pinctrl: remove duplicated include from pinctrl-xway.c
  pinctrl: sirf: remove sirfsoc_gpio_set_pull function
  pinctrl: fix return value in bcm2835_pinctrl_probe()
  pinctrl: remove duplicated include from pinctrl-bcm2835.c
  pinctrl: bcm2835: Use existing pointer to struct device
  pinctrl: samsung: use __devinit section for init code
