Subject: [PATCH] ASoC: ak4642: Return of_clk_add_provider to transfer the error
Return of_clk_add_provider() in order to transfer the error if it fails due
to insufficient memory allocation or failure to set clock defaults.
Fixes: 171a0138ab75 ("ASoC: ak4642: enable to use MCKO as fixed rate output pin on DT")
