I suggest if you need send another version of the series directly linking to the commit in the cover letter so that it won't take multiple hoops to find it if one wants to review the code and is not having all drm trees easily at hand. Here it is for the benefit of other pdx86 people: https://gitlab.freedesktop.org/drm/misc/kernel/-/commit/0cc6aadd7fc1e629b715ea3d1ba537ef2da95eec Acked-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com> I assume you want this to go through the drm tree where the helper already is?

This is the new API for allocating DRM bridges.
