Re: KASAN: use-after-free Read in v4l2_release (3)

[Dan Carpenter]

This would work but another approach would be to to allocate "usbvision"
with devm_kzalloc(&dev->dev,...  I believe that would postpone the free
enough to solve the use after free but I hadn't tested it yet.  But
other drivers do that so hopefully it works.
