Subject: [PATCH v2 7/8] net: ax88796: release platform device drvdata on probe error and module remove

From: Michael Schmitz <[email-masked]>
Date: Tue, 17 Apr 2018 14:08:14 +1200

The net device struct pointer is stored as platform device drvdata on
module probe - clear the drvdata entry on probe fail there, as well as
when unloading the module.
