Subject: [PATCH] mmc: davinci_mmc: Handle error for clk_enable
Git-commit: 09e7af76db02c74f2a339b3cb2d95460fa2ddbe4
Patch-mainline: v5.18-rc1
References: git-fixes
As the potential failure of the clk_enable(),
it should be better to check it and return error
if fails.
Fixes: bbce5802afc5 ("davinci: mmc: updates to suspend/resume implementation")
