Subject: [PATCH 06/12] net: ethernet: ti: cpts: Handle error for clk_enable
Git-commit: 6babfc6e6fab068018c36e8f6605184b8c0b349d
Patch-mainline: v5.17-rc8
References: git-fixes
As the potential failure of the clk_enable(),
it should be better to check it and return error
if fails.
Fixes: 8a2c9a5ab4b9 ("net: ethernet: ti: cpts: rework initialization/deinitialization")
