[media] dvb_demux: fix deadlock in dmx_section_feed_release_filter()

2013-11-29T14:18:25+00:00

dmx_section_feed_release_filter() locks dvbdmx->mutex and
if the feed is still filtering, it calls feed->stop_filtering(feed).
stop_filtering() is implemented by dmx_section_feed_stop_filtering()
that first of all try to lock the same mutex: dvbdmx->mutex.
That leads to a deadlock.
It does not happen often in practice because all callers of
release_filter() stop filtering by themselves.
So the problem can happen in case of race condition only.
The patch releases dvbdmx->mutex before call to feed->stop_filtering(feed)
and reacquires the mutex after that.

[media] media: dvb-core: prepare for enabling irq in complete()

2013-10-02T09:48:13+00:00

Complete() will be run with interrupt enabled, so change to
spin_lock_irqsave().
These functions may be called inside URB->complete(), so use
spin_lock_irqsave().

[media] demux.h: Remove duplicated enum

2013-04-08T09:53:15+00:00

"enum dmx_ts_pes" and "typedef enum dmx_pes_type_t" are just the
same enum declared twice, since Kernel (2.6.12). There's no reason
to duplicate it there, and sparse complains about that:
	drivers/media/dvb-core/dmxdev.c:600:55: warning: mixing different enum types
So, remove the internal define, keeping just the external one.
Internally, use only "enum dmx_ts_pes", as it is too late to drop
dmx_pes_type_t from the userspace API.

[media] dvb: move the dvb core one level up

2012-08-14T02:08:14+00:00

just like the V4L2 core, move the DVB core to drivers/media, as the
intention is to get rid of both "video" and "dvb" directories.
