Subject: iio: adc: rzg2l_adc: Convert dev_err() to dev_err_probe()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=a34dc289f89ecc4e967dfe6ec742aafdc5ae62f6;p=users%2Fjedix%2Flinux-maple.git

iio: adc: rzg2l_adc: Convert dev_err() to dev_err_probe()

Convert all occurrences of dev_err() in the probe path to dev_err_probe().
This improves readability and simplifies the code.
