[media] media: Drop FSF's postal address from the source code files

2017-01-27T13:38:09+00:00

Drop the FSF's postal address from the source code files that typically
contain mostly the license text. Of the 628 removed instances, 578 are
outdated.

The patch has been created with the following command without manual edits:

git grep -l "675 Mass Ave\|59 Temple Place\|51 Franklin St" -- \
	drivers/media/ include/media|while read i; do i=$i perl -e '
open(F,"< $ENV{i}");
$a=join("", );
$a =~ s/[ \t]*\*\n.*You should.*\n.*along with.*\n.*(\n.*USA.*$)?\n//m
	&& $a =~ s/(^.*)Or, (point your browser to) /$1To obtain the license, $2\n$1/m;
close(F);
open(F, "> $ENV{i}");
print F $a;
close(F);'; done

[media] Raise adapter number limit

2016-11-23T15:28:43+00:00

The current limit is too low for latest cards with 8+ tuners on a single slot.
IMHO, the most appropriate minimum default is 16.

[media] dvbdev: split dvb_unregister_device()

2016-11-18T17:02:39+00:00

dvb_unregister_device() has a major problem: it combines unregistering
with memory disposal.  Sometimes, it is necessary to unregister a
device, but no memory can be freed yet, because a process still has a
(stale) file handle.  Therefore, we need to split
dvb_unregister_device().  This will allow sanitizing a few callers.

With my new design, dvb_unregister_device() appears misnamed, but to
reduce patch noise, I'm not renaming it just yet.

[media] mxl111sf: Add a tuner entity

2016-01-11T14:19:26+00:00

While mxl111sf may have multiple frontends, it has just one
tuner. Reflect that on the media graph.

[media] dvbdev: create links on devices with multiple frontends

2016-01-11T14:19:26+00:00

Devices like mxl111sf-based WinTV Aero-m have multiple
frontends, all linked on the same demod. Currently, the
dvb_create_graph() function is not smart enough to create
multiple links. Fix it.

[media] dvbdev: Add RF connector if needed

2016-01-11T14:19:25+00:00

Several pure digital TV devices have a frontend with the tuner
integrated on it. Add the RF connector when dvb_create_media_graph()
is called on such devices.

Tested with siano and dvb_usb_mxl111sf drivers.

[media] dvb core: must check dvb_create_media_graph()

2016-01-11T14:18:59+00:00

If media controller is enabled and mdev is filled, it should
ensure that the media graph will be properly initialized.

Enforce that.
