Subject: rtc: m41t80: return NULL rather than a plain 0 integer
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7caadcfa8a7c6f8e754d982b99d959a222e7f863;p=linux.git

rtc: m41t80: return NULL rather than a plain 0 integer

Function m41t80_sqw_register_clk returns a pointer to struct clk,
so returning a plain 0 integer isn't good practice. Fix this by
returning a NULL instead.
