V4L/DVB (5916): ivtv: fix pause/continue/play handling
Pausing a decoder followed by a Play command would do nothing. Fixed. Pausing a decoder running at non-standard speed following by a Continue would reset the speed to 100%. Fixed. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
