    rtc: fix deadlock · 38c052f8
    Ingo Molnar authored
    if get_rtc_time() is _ever_ called with IRQs off, we deadlock badly
    in it, waiting for jiffies to increment.
    
    So make the code more robust by doing an explicit mdelay(20).
    
    This solves a very hard to reproduce/debug hard lockup reported
    by Mikael Pettersson.
