[PATCH 0/2] drm/bridge: start moving towards struct drm_edid

This is just the first two patches of a lengthy series that I'm not
really sure how to proceed with. Basically the series converts all of
drm/bridge to the new struct drm_edid infrastructure. It's safer than
struct edid, because it contains meta information about the allocated
size of the EDID, instead of relying on the size (number of extensions)
originating from outside of the kernel.

The rest is at [1]. The commit messages are lacking, and I don't really
have the toolchain to even build test most of it. But I think this is
where drm/bridge should go. Among all of drm, I think bridge has the
most uses of struct edid that do not originate from the drm_get_edid()
family of functions, which means the validity checks are somewhat
inconsistent, and having the meta information is more crucial.

Bridge maintainers, please instruct how to best proceed with this.


Thanks,
Jani.
