Merge tag 'mfd-for-linus-3.6-2' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6

Pull mfd fixes from Samuel Ortiz:
 "This is the remaining MFD fixes for 3.6, with 5 pending fixes:

   - A tps65217 build error fix.
   - A lcp_ich regression fix caused by the MFD driver failing to
     initialize the watchdog sub device due to ACPI conflicts.
   - 2 MAX77693 interrupt handling bug fixes.
   - An MFD core fix, adding an IRQ domain argument to the MFD device
     addition API in order to prevent silent and potentially harmful
     remapping behaviour changes for drivers supporting non-DT
     platforms."
