3.19.8-ckt6 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Tomas Winkler <tomas.winkler@xxxxxxxxx> commit 154322f47376fed6ab1e4b350aa45fffa15a61aa upstream. chrdev_open() increases reference counter on cdev->owner. Instead of assigning the owner to mei subsystem, the owner has to be set to the underlaying HW module (mei_me or mei_txe), so once the device is opened the HW module cannot be unloaded.
