Subject: [GIT PULL] Linux Media vimc update for 6.11-rc1

Hi Mauro,

Please pull the following vimc next update for Linux 6.11-rc1.

This vimc update for Linux 6.11-rc1 consists of a nine patch series
that cleans up and improves the vimc driver, with the end goal of
converting it to the V4L2 subdev active state API. The goal of
this exercise is to make the API used by a virtual test driver, to
increase test coverage.

The series starts with 4 random cleanups, to avoid unnecessary
iterations (1/9), constify structures (2/9 and 3/9) and rename a
weirdly-named enum (4/9). Patch 5/9 then centralizes the subdev
internal_ops initialization to prepare for the switch to the active
state API. The remaining patches (6/9 to 9/9) convert the vimc entities
to the new API one by one.

The result has been tested using the libcamera unit tests, which make
extensive use of the vimc driver, as well as with v4l2-compliance. The
latter reports 4 errors, but they occur already with the latest stage
master branch.

diff is attached.

thanks,
-- Shuah
