media: docs: pvrusb2: replace http references with https ones

2020-07-19T05:57:27+00:00

PVRUSB2 VIDEO4LINUX DRIVER: Replace HTTP links with HTTPS ones

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

media: samsung: Rename Samsung and Exynos to lowercase

2020-07-04T10:41:12+00:00

Fix up inconsistent usage of upper and lowercase letters in "Samsung"
and "Exynos" names.

"SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked
names.  Therefore they should be written with lowercase letters starting
with capital letter.

The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.

Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in
privacy/legal statements on
https://www.samsung.com/semiconductor/privacy-global/).

We never use _ in directory names in the media subsystem, so
rename to test-drivers instead for consistency.

Also update MAINTAINERS with the new path.

media: Documentation/media: drop/fix vivi references

2020-04-16T08:37:49+00:00

The vivi.c driver has long gone, but v4l2-videobuf.rst still
refers to it. Just drop that reference since it is no longer valid
or relevant (videobuf is deprecated).

The QUERYCAP documentation also made a reference to is, but there
vivi could just be replaced by vivid, the vivi successor.
