Subject: power: supply: bd71828: Use dev_err_probe()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=12bdf471e374b34cb0e48b29bb9eb9127ed26fc5;p=thirdparty%2Fkernel%2Fstable.git

power: supply: bd71828: Use dev_err_probe()

The driver uses separate error printing and error returning at probe()
for locations where the error value is hard-coded and can't be
EPROBE_DEFER. This helps to omit the extra return value check which is
done in dev_err_probe().

Using the dev_err_probe() has some other benefits besides handling the
-EPROBE_DEFER though, like standardizing the print for error numbers.
Some believe thes outweigh the benefit of skipping the extra check.

Use dev_err_probe() consistently in the bd71828 power-supply probe.
