From 7210c678202bb3107085bffeb63f66a9b8ba1c85 Mon Sep 17 00:00:00 2001 From: Kyle McMartin <kyle@shortfin.cabal.ca> Date: Sat, 20 Oct 2007 13:23:00 -0700 Subject: [PATCH] [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.
