From 57bb1ee6034046be70aed33fd6d447bb2b7261fa Mon Sep 17 00:00:00 2001 From: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed, 4 Nov 2020 11:04:21 +0100 Subject: drm: Compile out legacy chunks from struct drm_device This means some very few #ifdef in code, but it allows us to enlist the compiler to make sure this stuff isn't used anymore. More important, only legacy drivers change drm_device (for the legacy_dev_list shadow attach management), therefore this is prep to allow modern drivers to have a const driver struct. Which is nice, because there's a ton of function pointers in there.
