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: 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: ca.h: split typedefs from structs

2017-09-05T09:48:39+00:00

Using typedefs inside the Kernel is against CodingStyle, and
there's no good usage here.

Just like we did at frontend.h, at commit 0df289a209e0 ("[media] dvb:
Get rid of typedev usage for enums"), let's keep those typedefs only
to provide userspace backward compatibility.

No functional changes.
