   4 Subject: [PATCH] pcf506xx.patch
   5  Moved shared PMU code from pcf50606.h and pcf50633.h (which prevented inclusion
   6  of both at the same time) to pcf506xx.h
   7
   8 - include/linux/pcf50606.h (struct pmu_voltage_rail, enum pmu_event, pmu_cb):
   9   moved to pcf506xx.h
  10 - include/linux/pcf50633.h (struct pmu_voltage_rail, enum pmu_event, pmu_cb):
  11   moved to pcf506xx.h
