Subject: Staging: iio: Simplify return logic
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=da29461ccdf811b27a1cf53483ec2457fb4a6ae7;p=openwrt%2Fstaging%2Fblogic.git

Staging: iio: Simplify return logic

This patch removes the conditional return of the ade77*_probe functions
based on the return values of iio_device_register as the latter
returns 0 or ret, the same as the checked values.

Warning found by coccinelle.
