   4 Subject: [PATCH] add-pcf50633-06-RTC_AIE-ioctl
   5
   6 Hey,
   7
   8 the legacy application 'atd' from Russ Nelson/Nils Faerber, used by Qtopia, to
   9 schedule alarms currently fails to start as the the above ioctl is failing.
  10 The other drivers in drivers/rtc implement the above ioctl and we can
  11 implement it too.
  12
  13 The code to mask/unmask the RTC alarm is copied from the set_alarm routine and
  14 adapted to use the reg_set_bit_mask and reg_set_clear_mask.
  15
  16 It is compiling, so it must work. Please welcome me the lkml way ;)
