The wakealarm attribute is currently not exposed in the sysfs interface as the device has not been set as doing wakealarm when device_register is called. Changing the order of the calls fixes that problem. Interrupts are cleared in check_rtc_status prior to requesting the interrupt. This is only set if an irq is defined. If irq registration fails then set wakeup_capable to false. With this change the sysfs wakealarm attribute will be left visible but it is non functional. rtcwake still returns that the device is not enabled for wakeup. Signed-off-by: Phil Reid <preid@electromag.com.au> --- Notes: Changes from v1: - Don't register the irq before device_register call. but set the capability if a irq is defined. Unset wakeup capability if irq registration fails. drivers/rtc/rtc-ds3232.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-)
