85cb78b564 [media] DocBook: Add entry IDs for enum fe_caps
enum fe_caps is documented at FE_GET_INFO ioctl. Add xrefs
for each entry there. This makes the hyperlinks at frontend.h
to go directly to the right documentation.

2695e66f94 [media] DocBook: handle enums on frontend.h
In order to be sure that all enum definitions will be documented,
let's parse the enum values and add xref links to them.

Lots of missing references will be risen as we miss adding
id's to those symbols at the documentation. Next patches will
fix this.

7f3c2e1d1d [media] cx231xx: fix compiler warning
Fix this compiler warning by allocating a structure to read the eeprom instead
of doing it on the stack and worse: the eeprom array is static, so that can
cause problems if there are multiple cx231xx instances.

cx231xx-cards.c: In function 'cx231xx_card_setup':
cx231xx-cards.c:1110:1: warning: the frame size of 2064 bytes is larger than 2048 bytes [-Wframe-larger-than=]
 }
 ^

I did consider removing the code altogether since the result is actually
not used at the moment, but I decided against it since it is used in other
drivers and someone might want to start using it in this driver as well. And
then it is useful that the code is already there.

061ddda681 [media] v4l2-dv-timings: add interlace support in detect cvt/gtf
Extend detect_cvt/gtf API to indicate the format type (interlaced
or progressive). In case of interlaced, the vertical front and back
porch and vsync values for both (odd,even) fields are considered to
derive image height. Populated vsync, vertical front, back porch
values in bt timing structure for even and odd fields and updated
the flags appropriately.

Also modified the functions calling the detect_cvt/gtf(). As of now
these functions are calling detect_cvt/gtf() with interlaced flag
set to false.

dc0cf4cfed [media] v4l2-dv-timing: avoid rounding twice in gtf hblank calc
Currently, in gtf hblank calculations, the rounding is used twice,
one at intermediate division and one at final state where hblank

video.

c70316f2a1 [media] vivid: move PRINTSTR to separate functions
Commit 84cb7be43c broke vivid-tpg
(uninitialized variable p).

This patch takes a different approach: four different functions are
created, one for each PRINTSTR version.

In order to avoid the 'the frame size of 1308 bytes is larger than 1024
bytes' warning I had to mark those functions with 'noinline'. For
whatever reason gcc seems to inline this aggressively and it is doing
weird things with the stack.

I tried to read the assembly code, but I couldn't see what exactly it
was doing on the stack.
