From e329331aedeca0f2a7e15bd26a829ee1619c05e0 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Thu, 3 Nov 2005 01:02:40 +0900 Subject: [PATCH] Remove mips_rtc_lock The mips_rtc_lock is no longer needed because RTC operations should be protected already by other mechanism. (rtc_lock, local_irq_save, etc.) Also, locking whole rtc_get_time/rtc_set_time should be avoided while some RTC routines might take very long time (a few seconds).
