text[s] is a signed char, so using that as index into the font8x16 array
can result in negative indices. Cast it to u8 to be safe.

<title>media: v4l2-tpg: fix kernel oops when enabling HFLIP and OSD</title>

<id>urn:sha1:250854eed5d45a73d81e4137dfd85180af6f2ec3</id>
<content type='text'>
When the OSD is on (i.e. vivid displays text on top of the test pattern), and
you enable hflip, then the driver crashes.

The cause turned out to be a division of a negative number by an unsigned value.
You expect that -8 / 2U would be -4, but in reality it is 2147483644 :-(

<content type='text'>
The CTA-861 standards have been updated to refer to opRGB instead
of AdobeRGB. The official standard is in fact named opRGB, so
switch to that.

The two old defines referring to ADOBERGB in the public API are
put under #ifndef __KERNEL__ and a comment mentions that they are
deprecated.

Z16 support is identical to Y16, so that's easy to add.

When logging the current TPG state detect if we are generating
a Y'CbCr or HSV pattern and report one or the other instead of
both, which is confusing.

<title>treewide: Use array_size() in vzalloc()</title>

<id>urn:sha1:fad953ce0b22cfd352a9a90b070c34b8791e6868</id>
<content type='text'>
The vzalloc() function has no 2-factor argument form, so multiplication
factors need to be wrapped in array_size(). This patch replaces cases of:

        vzalloc(a * b)

with:
        vzalloc(array_size(a, b))

as well as handling cases of:

        vzalloc(a * b * c)

with:

        vzalloc(array3_size(a, b, c))

This does, however, attempt to ignore constant size factors like:

        vzalloc(4 * 1024)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:
