USB: fix DoS in pwc USB video driver the pwc driver has a disconnect method that waits for user space to close the device. This opens up an opportunity for a DoS attack, blocking the USB subsystem and making khubd's task busy wait in kernel space. This patch shifts freeing resources to close if an opened device is disconnected. Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
