[PATCH] ASoC: atmel_ssc_dai: Handle errors for clk_enable

From: Jiasheng Jiang
Date: Tue Mar 01 2022 - 04:06:54 EST


As the potential failure of the clk_enable(),
it should be better to check it and return error if fals.

Fixes: cbaadf0f90d6 ("ASoC: atmel_ssc_dai: refactor the startup and shutdown")
