In cx18_vapi(), when cx is NULL, it is still used on line 833:
CX18_ERR("cx == NULL (cmd=%x)\n", cmd);
v4l2_err(&cx->v4l2_dev, fmt , ## args)
Thus, a possible null-pointer dereference may occur.
This bug is found by a static analysis tool STCheck written by us.
I do not know how to correctly fix this bug, so I only report it.
Best wishes,
Jia-Ju Bai
