[PATCH 5.2 024/131] clk: sprd: Add check for return value of sprd_clk_regmap_init()
From: Greg Kroah-Hartman
Date: Mon Aug 05 2019 - 09:30:18 EST
[ Upstream commit c974c48deeb969c5e4250e4f06af91edd84b1f10 ]
sprd_clk_regmap_init() doesn't always return success, adding check
for its return value should make the code more strong.
