Since all time members of the alarm data is initialized to -1 the drivers
are responsible to set the tm_sec member to 0.
Fixes: d68778b80dd7 ("rtc: initialize output parameter for read alarm to
"uninitialized"")

Hello,
while going through all .read_alarm functions I wondered about rtc-sa1100
which only sets .enabled and .pending but no time.
Best regards
