Subject: iio: magnetometer: ak8975: Add missed pm_runtime_put_autosuspend() call
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=e94944d7364d3ddb273539492f9bd9c9a622549a;p=thirdparty%2Flinux.git

iio: magnetometer: ak8975: Add missed pm_runtime_put_autosuspend() call

On the failure in the ak8975_read_axis() the PM runtime gets unbalanced.
Balance it by calling pm_runtime_put_autosuspend() on error path as well.
