[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.
