The comments in cmos_read_alarm() and cmos_set_alarm() do not apply to
current code, replace them.
These comments were added in
commit fbb974ba693b ("rtc: cmos: Do not export alarm rtc_ops when we do not support alarms")
which introduced a separate struct rtc_class_ops, which was used when
the device did not support RTC alarms. The functions cmos_read_alarm()
and cmos_set_alarm() were called not only from the rtc_op struct, but
also explicitly, so they had to independently check for RTC alarm
support.
The separate rtc_class_ops structure was later removed in
commit 30f5bd537fdb ("rtc: cmos: remove cmos_rtc_ops_no_alarm")
but the comments remained and now are obsolete.
