Subject: clk: rockchip: don't return NULL when registering mmc branch fails
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=022dce0bd03905251de6cdd491a292818eaf3b89;p=deliverable%2Flinux.git

clk: rockchip: don't return NULL when registering mmc branch fails

Avoid return NULL if rockchip_clk_register_mmc fails, otherwise
rockchip_clk_register_branches print "unknown clock type". The acutal
case is that it's a known clock type but we fail to regiser it, which
may makes user confuse the reason of failure.
