V4L/DVB (8022): saa7134: fix race between opening and closing the device
decrementing dev->empress_users should be done as last action of ts_release, because it sleeps and write access to dev->empress_started is not protected in any way (additionally closing thread could mute audio after opening thread unmuted it) Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
