Merge tag 'pinctrl-v3.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw...

Pull pinctrl fixes from Linus Walleij:
 "First round of pin control fixes for v3.14:

   - Protect pinctrl_list_add() with the proper mutex.  This was
     identified by RedHat.  Caused nasty locking warnings was rootcased
     by Stanislaw Gruszka.

   - Avoid adding dangerous debugfs files when either half of the
     subsystem is unused: pinmux or pinconf.

   - Various fixes to various drivers: locking, hardware particulars, DT
     parsing, error codes"
