Merge tag 'pinctrl-v3.18-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin-control fixes from Linus Walleij:
 "This kernel cycle has been calm for both pin control and GPIO so far
  but here are three pin control patches for you anyway, only really
  dealing with Baytrail:

   - Two fixes for the Baytrail driver affecting IRQs and output state
     in sysfs
   - Use the linux-gpio mailing list also for pinctrl patches"

* tag 'pinctrl-v3.18-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:
  pinctrl: baytrail: show output gpio state correctly on Intel Baytrail
  pinctrl: use linux-gpio mailing list
  pinctrl: baytrail: Clear DIRECT_IRQ bit
