This patch series drops the '- .. row 1' lines in the mediactl
documentation (the last media docs that used this), fixes incorrect
types in subdev-formats.rst and removes the __NEED_MEDIA_LEGACY_API
define.
The last two patches were also the first two patches in this older
patch series:
https://www.mail-archive.com/linux-media@vger.kernel.org/msg129417.html
These three should be uncontroversial and they simplify the other
media patches in that older patch series.
Regards,
Hans

The __NEED_MEDIA_LEGACY_API define is 1) ugly and 2) dangerous
since it is all too easy for drivers to define it to get hold of
legacy defines. Instead just define what we need in media-device.c
which is the only place where we need the legacy define
(MEDIA_ENT_T_DEVNODE_UNKNOWN).
