Merge tag 'pinctrl-fixes-for-v3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pinctrl fixes from Linus Walleij:
 "Here are a few pinctrl fixes for the v3.9 rc series:
   - Usecount bounds checking so we do not go below zero on mux
     usecounts.
   - Loop range checking in GPIO ranges in the DT range parser.
   - Proper print in debugfs for pinconf state.
   - Fix compilation bug in generic pinconf code.
   - Minor bugfixes to abx500 and mvebu drivers."
