From fcea8b27f985bc02fd7b040bbb5914227a0f49d7 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Fri, 16 May 2014 23:25:44 +0200 Subject: [PATCH] sparc32: fix sparse warnings in time_32.c Fix following warnings: time_32.c:63:1: warning: symbol 'rtc_lock' was not declared. Should it be static? time_32.c:357:13: warning: symbol 'time_init' was not declared. Should it be static? time_32.c:148:16: warning: dereference of noderef expression Add extern definition of rtc_lock in mc146818rtc.h. time_init() is called from init/main.c - add prototype to kernel.h. Use proper u32 __iomem * for master_l10_counter. Fix all users. Signed-off-by: Sam Ravnborg Signed-off-by: David S.
