9332ef9dbd scripts/spelling.txt: add "an user" pattern and fix typo instances
Fix typos and add the following to the scripts/spelling.txt:

  an user||a user
  an userspace||a userspace

I also added "userspace" to the list since it is a common word in Linux.
I found some instances for "an userfaultfd", but I did not add it to the
list.  I felt it is endless to find words that start with "user" such as
"userland" etc., so must draw a line somewhere.

35879ee476 [media] videodev2.h: go back to limited range Y'CbCr for SRGB and, ADOBERGB
This reverts 'commit 7e0739cd9c ("[media] videodev2.h: fix
sYCC/AdobeYCC default quantization range").

The problem is that many drivers can convert R'G'B' content (often
from sensors) to Y'CbCr, but they all produce limited range Y'CbCr.

To stay backwards compatible the default quantization range for
sRGB and AdobeRGB Y'CbCr encoding should be limited range, not full
range, even though the corresponding standards specify full range.

Update the V4L2_MAP_QUANTIZATION_DEFAULT define accordingly and
also update the documentation.

0751d33c27 [media] rc: change wakeup_protocols to list all protocol variants
For IR wakeup, a driver has to program the hardware to wakeup at a
specific IR sequence, so it makes no sense to allow multiple wakeup
protocols to be selected. In the same manner the sysfs interface only
allows one scancode to be provided.

In addition, we need to know the specific variant of the protocol.

In short, these changes are made to the wakeup_protocols sysfs entry:
 - list all the protocol variants rather than the protocol groups,
   e.g. "nec nec-x nec-32" rather than just "nec".
 - only allow one protocol variant to be selected rather than multiple
 - wakeup_filter can only be set once a protocol has been selected in
   wakeup_protocols.

This is an API change, however the only user of this API is the img-ir,
but the wakeup code was never merged to mainline, so it was never used.

20b8522736 [media] media: Rename graph and pipeline structs and functions
The media_entity_pipeline_start() and media_entity_pipeline_stop()
functions are renamed as media_pipeline_start() and media_pipeline_stop(),
respectively. The reason is two-fold: the pipeline struct is, rightly,
already called media_pipeline (rather than media_entity_pipeline) and what
this really is about is a pipeline. A pipeline consists of entities ---
and, well, other objects embedded in these entities.

As the pipeline object will be in the future moved from entities to pads
in order to support multiple pipelines through a single entity, do the
renaming now.

Similarly, functions operating on struct media_entity_graph as well as the
struct itself are renamed by dropping the "entity_" part from the prefix
of the function family and the data structure. The graph traversal which
is what the functions are about is not specifically about entities only
and will operate on pads for the same reason as the media pipeline.

The patch has been generated using the following command:

git grep -l media_entity |xargs perl -i -pe '
	s/media_entity_pipeline/media_pipeline/g;
	s/media_entity_graph/media_graph/g'

And a few manual edits related to line start alignment and line wrapping.

b9a4b13c77 [media] v4l: Add 16-bit raw bayer pixel formats
The formats added by this patch are:

	V4L2_PIX_FMT_SBGGR16
	V4L2_PIX_FMT_SGBRG16
	V4L2_PIX_FMT_SGRBG16

V4L2_PIX_FMT_SRGGB16 already existed before the patch. Rework the
documentation to match that of the other sample depths.

Also align the description of V4L2_PIX_FMT_SRGGB16 to match with other
similar formats.

15a04d4e76 docs-rst: auto-generate PDF image files
The PDF files that contain media images were actually generated
offline from their SVG or PNG source files.

Sphinx can handle PNG sources automatially. So, let's just
drop their PDF counterparts.

For SVG, however, Sphinx doesn't produce the right tags to
use the TexLive SVG support. Also, the SVG support is done via
shell execution, with is not nice.

So, while we don't have any support for SVG inside Sphinx
core or as an extension, move the logic to build them to Makefile,
producing the PDF images on runtime.

NOTE: due to the way Sphinx works, the PDF images should be
generated inside the Kernel source tree, as otherwise Sphinx
won't find it, not obeying what's specified by "O=" makefile
parameter.

PDF build on Kernel 4.9-rc? returns an error with Sphinx 1.3.x
and Sphinx 1.4.x, when trying to solve some cross-references.

The solution is to redefine the \DURole macro.

However, this is redefined too late. Move such redefinition to
LaTeX preamble and bind it to just the Sphinx versions where the
error is known to be present.

Tested by building the documentation on interactive mode:
	make PDFLATEX=xelatex -C Documentation/output/./latex

f5580d8d6f [media] cec: accept two replies for CEC_MSG_INITIATE_ARC
The CEC_MSG_INITIATE_ARC message is special since it is the ONLY
CEC message that accepts two possible valid replies:

CEC_MSG_REPORT_ARC_INITIATED and CEC_MSG_REPORT_ARC_TERMINATED.

So if the transmitted message is CEC_MSG_INITIATE_ARC and the remote
side replied with CEC_MSG_REPORT_ARC_INITIATED or CEC_MSG_REPORT_ARC_TERMINATED,
then a msg->reply value of CEC_MSG_REPORT_ARC_INITIATED or
CEC_MSG_REPORT_ARC_TERMINATED will match either reply.

I thought about either adding a second reply2 field, but that's ugly
for all other messages that have only one reply, and what if in the
future a new message is added that can have three replies?

Another option would be to add a cec_msg flag, but really, the combination
of CEC_MSG_REPORT_ARC_INITIATED and a reply value of one of the two
possible replies already functions as a flag.

Another advantage of this approach is that it is safe to re-use a
cec_msg struct. No need to zero a flags field or a reply2 field.

So since this really is an exception in the CEC specification, I
decided to implement it as an exception as well.

By default the CEC_MSG_USER_CONTROL_PRESSED/RELEASED messages
are passed on to the follower(s) only. If the new
CEC_LOG_ADDRS_FL_ALLOW_RC_PASSTHRU flag is set in the
flags field of struct cec_log_addrs then these messages are also
passed on to the remote control input subsystem and they will appear
as keystrokes.

This used to be the default behavior, but now you have to explicitly
enable it. This is done to force the caller to think about possible
security issues (e.g. if these messages are used to enter passwords).

e42c475418 [media] doc-rst: 16-bit BGGR is always 16 bits
The V4L2_PIX_FMT_SBGGR16 format is documented to contain samples of fewer
than 16 bits. However, we do have specific definitions for smaller sample
sizes. Therefore, this note is redundant from the API point of view.

Currently only two drivers, am437x and davinci, use the
V4L2_PIX_FMT_SBGGR16 pixelformat currently. The sampling precision is
understood to be 16 bits in all current cases.

Remove the note on sampling precision.
