[PATCH v1 2/5] rtc: rtc-cmos: Call rtc_wake_setup() from cmos_do_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

To reduce code duplication, move the invocation of rtc_wake_setup()
into cmos_do_probe() and simplify the callers of the latter.

No intentional functional impact.
