Subject: [PATCH v2] workqueue: use put_device() instead of kfree()
Date: Tue,  6 Mar 2018 15:35:43 +0530	[thread overview]
Message-ID: <1520330743-20445-1-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 in this function instead.
