[PATCH] rtc framewok: rtc_wkalrm.enabled reporting updates

a2db8dfc · David Brownell <[email protected]> · 2006-12-13 00:35:08 -08:00

Fix a glitch in the procfs dumping of whether the alarm IRQ is enabled: use
the traditional name (from drivers/char/rtc.c and many other places) of
"alarm_IRQ", not "alrm_wakeup" (which didn't even match the efirtc code, which
originated that reporting API).

Also, update a few of the RTC drivers to stop providing that duplicate status,
and/or to expose it properly when reporting the alarm state.  We really don't
want every RTC driver doing their own thing here...
