From a2db8dfce8d94fecae50128d912fec7980687a51 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Wed, 13 Dec 2006 00:35:08 -0800 Subject: [PATCH] [PATCH] rtc framewok: rtc_wkalrm.enabled reporting updates 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...
