4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Arvind Yadav <arvind.yadav.cs@xxxxxxxxx> [ Upstream commit a4eb490a41a0da3b1275fc7427084cf9ae2c3c1c ] Never directly free @dev after calling device_register(), even if it returned an error. Always use put_device() to give up the reference initialized.
