Subject: [PATCH v2] ssb: use put_device() if device_register fail
Date: Thu, 8 Mar 2018 10:39:49 +0530 [thread overview]
Message-ID: <1520485789-8550-1-git-send-email-arvind.yadav.cs@gmail.com> (raw)
Never directly free @dev after calling device_register(), even
if it returned an error! Always use put_device() to give up the
reference initialized.
