Pull MFD fixes from Samuel Ortiz:

 - A twl fix preventing a buffer overflow.

 - A wm5102 register patch fix.

 - A wm5110 error misreport fix.

 - Arizona fixes: Use the right array size when adding subdevices,
   correctly report underclocked events, synchronize register cache
   after reset.

 - A twl4030 fix for preventing the system to hang from an interrupt
   flood.
