Merge tag 'mfd-for-linus-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6

Pull MFD fixes from Samuel Ortiz:
 "This is the first pull request for MFD fixes for 3.8

  We have some build failure fixes (twl4030, vexpress, abx500 and
  tps65910), some actual runtime oops and lockup fixes (rtsx, da9052),
  and some more hypothetical NULL pointers dereferences fixes for
  pcf50633 and max776xx.

  Then we also have additional rtsx fixes for a correct switch output
  voltage and clock divider correctness for rtl8411 (rtsx driver), and
  irqdomain fix for db8550-prcmu, and some more cosmetic fixes for
  arizona and wm5102."
