media: usbvision: deprecate driver
The driver is deprecated and scheduled for removal by the end of 2020. The reason is that this driver is for old and obsolete hardware, and it produces a continuous stream of syzbot errors due to poor code. In order to prevent removal the following actions would have to be taken: - clean up the code - convert to the vb2 framework - fix the disconnect and free-on-last-user handling (i.e., add a release callback for struct v4l2_device and rework the code to use that correctly).
