Matthias Kaehlcke fcaf94c49a rpmsg: char: Fix race between the release of rpmsg_eptdev and cdev ... commit 7a534ae89e34e9b51acb5a63dd0f88308178b46a upstream. struct rpmsg_eptdev contains a struct cdev. The current code frees the rpmsg_eptdev struct in rpmsg_eptdev_destroy(), but the cdev is a managed object, therefore its release is not predictable and the rpmsg_eptdev could be freed before the cdev is entirely released. The cdev_device_add/del() API was created to address this issue (see commit '233ed09d7fda ("chardev: add helper function to register char devs with a struct device")'), use it instead of cdev add/del().
