Mauro Carvalho Chehab 901b9dd5e3 media: update/fix my e-mail on some places
There are two places pointing to an unexisting "m.chehab@kernel.org"
email. I never had such email, so, I'm unsure how it ends there.
Anyway, it is plain wrong.

While here, use my canonical e-mail on a bunch of places that
are pointing to another e-mail. The idea is that, from now on,
all places will be pointing to the same SMTP server.

Mauro Carvalho Chehab 3259081991 MAINTAINERS & files: Canonize the e-mails I use at files
From now on, I'll start using my @kernel.org as my development e-mail.

As such, let's remove the entries that point to the old
mchehab@s-opensource.com at MAINTAINERS file.

For the files written with a copyright with mchehab@s-opensource,
let's keep Samsung on their names, using mchehab+samsung@kernel.org,
in order to keep pointing to my employer, with sponsors the work.

For the files written before I join Samsung (on July, 4 2013),
let's just use mchehab@kernel.org.

For bug reports, we can simply point to just kernel.org, as
this will reach my mchehab+samsung inbox anyway.

Since commit 9b6192589b ("media: lirc: implement scancode sending"),
and commit de142c3241 ("media: lirc: implement reading scancode")
the lirc features ioctl for raw IR devices advertises two modes for
sending and receiving.

The lirc daemon now fails to detect a raw IR device, both for transmit
and receive.

To fix this, do not advertise the scancode mode in the lirc features
for raw IR devices (however do keep it for scancode devices). The mode
can still be used via the LIRC_SET_{REC,SEND}_MODE ioctl.

Athanasios Oikonomou f9d7912619 media: dvb_frontend: add physical layer scrambling support
This commit adds a new property DTV_SCRAMBLING_SEQUENCE_INDEX.

This 18 bit field, when present, carries the index of the DVB-S2 physical
layer scrambling sequence as defined in clause 5.5.4 of EN 302 307.
There is no explicit signalling method to convey scrambling sequence index
to the receiver. If S2 satellite delivery system descriptor is available
it can be used to read the scrambling sequence index (EN 300 468 table 41).

By default, gold scrambling sequence index 0 is used. The valid scrambling
sequence index range is from 0 to 262142.

Increase the DVB API version in order userspace to be aware of the changes.

Sean Young dde7edff35 media: lirc: when transmitting scancodes, block until transmit is done
The semantics for lirc IR transmit with raw IR is that the write call
should block until the IR is transmitted. Some drivers have no idea
when this actually is (e.g. mceusb), so there is a wait.

This is useful for userspace, as it might want to send a IR button press,
a gap of a predefined number of milliseconds, and then send a repeat
message.

It turns out that for transmitting scancodes this feature is even more
useful, as user space has no idea how long the IR is. So, maintain
the existing semantics for IR scancode transmit.

Mauro Carvalho Chehab 259a41d9ae media: dvb_frontend: fix return values for FE_SET_PROPERTY
There are several problems with regards to the return of
FE_SET_PROPERTY. The original idea were to return per-property
return codes via tvp->result field, and to return an updated
set of values.

However, that never worked. What's actually implemented is:

- the FE_SET_PROPERTY implementation doesn't call .get_frontend
  callback in order to get the actual parameters after return;

- the tvp->result field is only filled if there's no error.
  So, it is always filled with zero;

- FE_SET_PROPERTY doesn't call memdup_user() nor any other
  copy_to_user() function. So, any changes to the properties
  will be lost;

- FE_SET_PROPERTY is declared as a write-only ioctl (IOW).

While we could fix the above, it could cause regressions.

So, let's just assume what the code really does, updating
the documentation accordingly and removing the logic that
would update the discarded tvp->result.

Mauro Carvalho Chehab bb98e6d280 media: dmx.h: add kernel-doc markups and use it at Documentation/
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 :-)

Mauro Carvalho Chehab 2889017c92 media: dmx.h: get rid of GET_DMX_EVENT
This seems to be a pure fictional API :-)

It only exists at the DVB book, with no code implemeting it.

So, just get rid of it.

So, get rid of it.

Use a table to document the supported bandwidths. That makes
it clearer to readers.
