mmc: uniphier-sd: Fix an error handling path in uniphier_sd_probe()
commitb03aec1c1f
upstream. A 'uniphier_sd_clk_enable()' call should be balanced by a corresponding 'uniphier_sd_clk_disable()' call. This is done in the remove function, but not in the error handling path of the probe. Add the missing call. Fixes:3fd784f745
