vfio-pci: Fix remove path locking Locking both the remove() and release() path results in a deadlock that should have been obvious. To fix this we can get and hold the vfio_device reference as we evaluate whether to do a bus/slot reset. This will automatically block any remove() calls, allowing us to remove the explict lock. Fixes 61d792562b53. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Cc: stable@vger.kernel.org [3.17]
