rpmsg: char: Fix race between the release of rpmsg_eptdev and cdev (2022-01-17 16:39:58 -0600)
---------------------------------------------------------------- rpmsg fixes for v5.17-rc1
The cdev cleanup in the rpmsg_char driver was not performed properly, resulting in unpredicable behaviour when the parent remote processor is stopped with any of the cdevs open by a client.
The two patches transitions the implementation to use cdev_device_add() and cdev_del_device(), to capture the relationship between the two objects, and relocates the incorrectly placed cdev_del().
