[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.

[media] DVB: improve handling of TS packets containing a raised TEI bit

2012-08-13T22:51:33+00:00

When the TEI bit is raised, we should not trust any of the contents of
the packet in question, including but not limited to its PID number.

Considering that we don't trust the PID number of this packet, we should
not proceed to check the packet counter (if dvb_demux_tscheck is set).

We should expect to see at least one discontinuity after a bad packet is
received, so any time a TEI is detected, a following TS packet counter
mismatch is to be expected.

There is no real reason to ever allow bad packets to pass through the
kernel demux, other than for purposes of attempting error correction via
software or statistical information.

However, since we have always passed these bad packets though the demux,
we should not change this default behavior.

Without altering module options, this patch merely prevents the
TS packet counter check on packets containing a raised TEI.

If module option dvb_demux_feed_err_pkts is set to 0, the kernel demux
will drop these error packets entirely, preventing any possibility of
corruption caused by userspace programs that are expecting valid data.

[media] dvb: get rid of fe_ioctl_override callback

2012-08-13T19:34:03+00:00

This callback were meant to allow overriding a FE callback, before its
call, but it is not really needed, as the callback can be intercepted
after tuner attachment.

Worse than that, only DVBv3 calls are intercepted this way, so a DVBv5
application will produce different effects than a DVBv3 one.

So, get rid of it.

[media] dvb core: remove support for post FE legacy ioctl intercept

2012-08-12T10:33:30+00:00

This DVB_FE_IOCTL_POST isn't used, so remove it.

Also, intercepting ioctl's like that only works with legacy ioctl's,
due to the way it was implemented. so this design is broken.
Document it.

[media] move dvb-usb-ids.h to dvb-core

2012-08-05T22:53:26+00:00

While this header were meant to be used just by dvb-usb driver, it
is now being used also by dvb-usb-v2 and cx231xx. So, move it to a
better place.

[media] dvb-core: Release semaphore on error path dvb_register_device()

2012-07-06T22:36:27+00:00

There is a missing "up_write()" here. Semaphore should be released
before returning error value.

[media] tuner, xc2028: add support for get_afc()

2012-07-04T05:46:58+00:00

Implement API support to return AFC frequency shift, as this device
supports it. The only other driver that implements it is tda9887,
and the frequency there is reported in Hz. So, use Hz also for this
tuner.
