-Subject: [PATCH 357/381] rtc: ds1307: ensure that any pending alarm is cleared
- before a new alarm is enabled
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-If a previously-set alarm was disabled and then triggered, it may still
-be pending when a new alarm is configured.
-
-Then, if the alarm is enabled before the pending alarm is cleared, then
-an interrupt is immediately raised.
-
-Unfortunately, when the alarm is cleared and enabled during the same I²C
-block write, the chip (at least the DS1339 I have) considers that the
-alarm is enabled before it is cleared, and raises an interrupt.
-
-This patch ensures that the pending alarm is cleared before the alarm is
-enabled.
