   7 pcf50633 remove suspend_enable/disable regulator functions
   8
   9 Since we don't switch to PMU.standby, on suspend we should not
  10 be defining these.
  11
  12 Btw, this fixes the WSOD I observed on andy-tracking and also
  13 gets rid of the regulator related backtrace seen upon resume.
