[PARISC] fix uninitialized variable warning in asm/rtc.h
get_rtc_time, in the case that PDC returns that the battery is bad, returns an unmodified rtc_time arg to the caller, which then uses uninitialized values. Fix this by memset-ing the arg with zeroes, so it will at least be cleared if we return failure. Spotted by John David Anglin. Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>
