Subject: clk: sprd: Add check for return value of sprd_clk_regmap_init()
X-Git-Tag: v5.4-rc1~535^2~1^5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c974c48deeb969c5e4250e4f06af91edd84b1f10;p=platform%2Fkernel%2Flinux-rpi.git

clk: sprd: Add check for return value of sprd_clk_regmap_init()

sprd_clk_regmap_init() doesn't always return success, adding check
for its return value should make the code more strong.
