[PATCH] RTC subsystem: proc interface Add the proc interface to the RTC subsystem. The first RTC driver which registers with the class will be accessible by /proc/driver/rtc . This is required for compatibility with the standard RTC driver and to avoid breaking any user space application which may erroneusly rely on this.

rtc-proc: permit the /proc/driver/rtc device to use other devices To get time information via /proc/driver/rtc, only the first device (rtc0) is used. If the rtcN (eg. rtc1 or rtc2) is used for the system clock, there is no way to get information of rtcN via /proc/driver/rtc. With this patch, the time data can be retrieved from the system clock RTC. If the RTC_HCTOSYS_DEVICE is not defined, then rtc0 is used by default.

rtc: fix snprintf() checking in is_rtc_hctosys() The scnprintf() function silently truncates the printf() and returns the number bytes that it was able to copy (not counting the NUL terminator). Thus, the highest value it can return here is "NAME_SIZE - 1" and the overflow check is dead code. Fix this by using the snprintf() function which returns the number of bytes that would have been copied if there was enough space and changing the condition from "> NAME_SIZE" to ">= NAME_SIZE".

[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...
