rtc: simplify implementations of read_alarm
Since commit d68778b80dd7 ("rtc: initialize output parameter for read alarm to "uninitialized"") there is no need to explicitly set unsupported members to -1. So drop the respective assignments from drivers. Signed-off-by: Uwe Kleine-König <uwe@kleine-koenig.org> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>
