Series | drm/panel: Make panel drivers use existing DSI write macros | expand |
Hi Javier, Could you please also cc maintainers on the actual macro addition since it's hard to review without seeing what the code gets changed to (especially when there's multiple revisions). I assume https://lore.kernel.org/dri-devel/20221228014757.3170486-2-javierm@redhat.com/ is the right one?
