Subject: ASoC: codecs: wcd934x: Handle nicer probe deferral and simplify with dev_err_probe()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=9ea22713227397b56a2b36a68c8bda13f0b43d70;p=users%2Fjedix%2Flinux-maple.git

ASoC: codecs: wcd934x: Handle nicer probe deferral and simplify with dev_err_probe()

wcd934x_codec_parse_data() function is called only from probe(), so
printing errors on resource acquisition is discouraged, because it can
pollute dmesg in case of probe deferral.  The actual deferral is here
unlikely, but still the code is a bit simpler with dev_err_probe().
