media: pvrusb2: fix memory leak in pvr_probe
commit 945a9a8e upstream. The error handling code in pvr2_hdw_create forgets to unregister the v4l2 device. When pvr2_hdw_create returns back to pvr2_context_create, it calls pvr2_context_destroy to destroy context, but mp->hdw is NULL, which leads to that pvr2_hdw_destroy directly returns. Fix this by adding v4l2_device_unregister to decrease the refcount of usb interface. Reported-by:<syzbot+77b432d57c4791183ed4@syzkaller.appspotmail.com> Signed-off-by:
