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.
