[PATCH] net: ethernet: ti: cpts: Handle error for clk_enable
Posted by Jiasheng Jiang 4 years, 3 months ago
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")
