[PATCH] rtc framewok: rtc_wkalrm.enabled reporting updates
Browse files Browse the repository at this point in the history
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...
