Merge tag 'pinctrl-fixes-v3.10-3' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin-control fixes from Linus Walleij:
 - Six patches fixing up the suspend/resume and wakeup handling of the
   Samsung and Exynos drivers.
 - Errorpath fixes for four different drivers.  All on the probe()
   errorpath.
 - Make the debugfs code for pin config take the right mutex.
