Subject: hwmon: (pmbus_core) Fix pmbus_is_enabled()
From: Patrick Rudolph <patrick.rudolph@xxxxxxxxxxxxx>
commit 55aab08f1856894d7d47d0ee23abbb4bc4854345 upstream.
Refactor pmbus_is_enabled() to return the status without any additional
processing as it is already done in _pmbus_is_enabled().
Fixes: df5f6b6af01c ("hwmon: (pmbus/core) Generalise pmbus get status")
