Subject: iio: adc: meson_saradc: Simplify with dev_err_probe()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a3e584fab675b833e9923a0f5e76031b027525d9;p=linux.git

iio: adc: meson_saradc: Simplify with dev_err_probe()

Common pattern of handling deferred probe can be simplified with
dev_err_probe().  Less code and also it prints the error value.
