From: Denis Efremov <efremov@xxxxxxxxx>
commit f170d44bc4ec2feae5f6206980e7ae7fbf0432a0 upstream.
The id pointer can be NULL in rsi_probe(). It is checked everywhere except
for the else branch in the idProduct condition. The patch adds NULL check
before the id dereference in the rsi_dbg() call.
Fixes: 54fdb318c111 ("rsi: add new device model for 9116")
