[PATCH] ASoC: mxs-saif: Add variable dev to simplify code

From: Tang Bin
Date: Wed Apr 29 2020 - 05:40:20 EST


Add variable 'dev' to make the code cleaner in the function
mxs_saif_probe(). And now that the function mxs_saif_mclk_init()
have defined the variables 'ret' as the error returned value,
then it should be used instead in this place.
