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