Hyunwoo Kim e504729496 fbdev: smscufx: Fix use-after-free in ufx_ops_open() 
commit 5610bcfe8693c02e2e4c8b31427f1bdbdecc839c upstream.

A race condition may occur if the user physically removes the
USB device while calling open() for this device node.

This is a race condition between the ufx_ops_open() function and
the ufx_usb_disconnect() function, which may eventually result in UAF.

So, add a mutex to the ufx_ops_open() and ufx_usb_disconnect() functions
to avoid race contidion of krefs.
