    Subjectstate of GEN_RTC vs rtc subsystem
    Date
    Is the functionality provided by drivers/char/gen_rtc.c completely  
    handled by the rtc subsystem in drivers/rtc?

    I ask for two reasons:
    1. should we make it mutually exclusive in Kconfig
    2. I've enabled both and get (we'll my defconfig did):

    proc_dir_entry 'rtc' already registered
