From: "Dr. David Alan Gilbert" <[email protected]>
'bridge_init' is unused, I think following:
commit 6a1688ae8794 ("drm/bridge: ptn3460: Convert to I2C driver model")
(which is where a git --follow finds it)
Remove it.
Build tested.

Please rephrase the commit message following guidelines in
Documentation/process. Use Fixes tags if suitable.

I specifically don't want to use Fixes in these set because
there's no need for someone to backport this to older
kernels that use the original, and many backporters
use 'Fixes' as an automated means to find stuff they should
backport.
Other than that, is there something specific you think I've
missed?
(I'm also purposely being less certain here, because --follow
is showing it in a ptn3460 and I don't quite follow
why that changes it here).

It's not about missing things. It's about a way it is written.
Consider something like:
The commit aaaaaaa ("drm/bridge: foo bar") has dropped all the users of
the struct bridge_init from the exynos_dp_core, while retainng unused
structure definition. Later on the driver was reworked and the
definition migrated to the analogix_dp driver. Remove unused struct
bridge_init definition.

The mentioned commit is a correct one. Historically exynos_dp_core had
been creating the ptn3460 bridge manually. Later on this was fixed in
the ptn3640 driver and the code was dropped from exynos_dp_core.

OK, v2 sent with text close to that.

Ah OK; remember I don't know the actual structure of these devices
or the history.

It's all a part of the git history. I've just read it aloud for you.
