Subject: [PATCH] rtc: rtc-nuc900: use NULL instead of 0
Date: Mon, 19 Aug 2013 14:28:08 +0900 [thread overview]
Message-ID: <017d01ce9c9c$e347fc60$a9d7f520$@samsung.com> (raw)
check_rtc_access_enable() returns pointer, thus NULL should be
used instead of 0 in order to fix the following sparse warning:
drivers/rtc/rtc-nuc900.c:102:16: warning: Using plain integer as NULL pointer
