Currently, the IRQs are disabled when the rtc character device is closed. This means that the device needs to stay open to get alarms while the usual use case will open the device, set the alarm and close the device as is done in rtcwake. Keep the alarm functional on character device release so the platform can actually wakeup Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> --- drivers/rtc/rtc-mxc.c | 21 --------------------- 1 file changed, 21 deletions(-)
