Description
In the Linux kernel, the following vulnerability has been resolved:
s390/vfio_ccw: Cancel existing workqueues
The initialization of the io_work and crw_work workqueues begs the
question of whether they should be un-initialized. Add the corresponding
cleanup tags in _release_dev to ensure work isn't dispatched after
the private struct is free'd.
