From: Jean Delvare <jdelvare@suse.de>

commit 8759f9046550f463098148bf577ccd32cdb895e3 upstream.

Commit 454aee17f claims to convert driver emc1403 to use
devm_hwmon_device_register_with_groups, however the patch itself makes
use of hwmon_device_register_with_groups instead. As the driver remove
function was still dropped, the hwmon device is no longer unregistered
on driver removal, leading to a resource leak.
