Hello!
My laptop has a "hardwired" button that disconnects its webcam from USB.
I've noticed the following kernel NULL pointer dereference when unplugging
the webcam that way while an application is grabbing frames:
usb 1-1.4: USB disconnect, device number 3
uvcvideo 1-1.4:1.1: Failed to resubmit video URB (-19).
BUG: kernel NULL pointer dereference, address: 0000000000000000
#PF: supervisor read access in kernel mode
#PF: error_code(0x0000) - not-present page
PGD 0 P4D 0

This does not seem to be reproducible, so perhaps a race is involved.
Complete dmesg is attached.
Thanks.
Alexander
