Date: Thu May 24 2018 - 05:00:06 EST


4.14-stable review patch. If anyone has any objections, please let me know.

From: Arvind Yadav <arvind.yadav.cs@xxxxxxxxx>

[ Upstream commit 00ad691ab140b54ab9f5de5e74cb994f552e8124 ]

Never directly free @dev after calling device_register(), even
if it returned an error. Always use put_device() to give up the
reference initialized.
