media: dvb headers: make checkpatch happier

2017-09-05T11:10:24+00:00

Adjust dvb ca.h, dmx.h and frontend.h in order to make
checkpatch happier. Now, it only complains about the typedefs,
and those are there just to provide backward userspace
compatibility.

media: ca.h: document ca_msg and the corresponding ioctls

2017-09-05T10:23:28+00:00

Usually, CA messages are sent/received via reading/writing at
the CA device node. However, two drivers (dst_ca and firedtv-ci)
also implement it via ioctls.

Apparently, on both cases, the net result is the same.

Anyway, let's document it.

media: ca docs: document CA_SET_DESCR ioctl and structs

2017-09-05T10:23:07+00:00

The av7110 driver uses CA_SET_DESCR to store the descrambler
control words at the CA descrambler slots.

Document it.

media: net.h: add kernel-doc and use it at Documentation/

2017-09-05T10:22:42+00:00

As we did with frontend.h, ca.h and dmx.h, move the struct
definition to net.h.

That should help to keep it updated, as more stuff gets
added there.

media: frontend.h: Avoid the term DVB when doesn't refer to a delivery system

2017-09-05T10:22:13+00:00

The DVB term can either refer to the subsystem or to a delivery
system. Avoid it in the first case at the kernel-doc markups.

media: ca.h: document most CA data types

2017-09-05T10:10:33+00:00

For most of the stuff there, documenting is easy, as the
header file contains information.

Yet, I was unable to document two data structs:
	ca_msg and ca_descr

As those two structs are used by a few drivers, keep them.

media: ca.h: get rid of CA_SET_PID

2017-09-05T10:06:56+00:00

This ioctl seems to be some attempt to support a feature
at the bt8xx dst_ca driver. Yet, as said there, it
"needs more work". Right now, the code there is just
a boilerplate.

At the end of the day, no driver uses this ioctl, nor it is
documented anywhere (except for "needs more work").

So, get rid of it.

media: dmx.h: add kernel-doc markups and use it at Documentation/

2017-09-05T10:05:40+00:00

The demux documentation is pretty poor nowadays: most of the
structs and enums aren't documented at all.

Add proper kernel-doc markups for them and use it.

Now, the demux API data structures are fully documented :-)

No driver uses this ioctl, nor it is documented anywhere.

So, get rid of it.

media: dmx.h: get rid of DMX_GET_CAPS

2017-09-05T10:00:49+00:00

There's no driver currently using it; it is also not
documented about what it would be supposed to do.

So, get rid of it.
