This series is a follow-up of the [1] in which I introduced a check for valid formats on drm_gem_fb_create(). During the discussion, I realized that would be a better idea to put the check inside framebuffer_check() so that it wouldn't be needed to hit any driver-specific code path when the check fails. Therefore, add the valid format check inside framebuffer_check() and remove the same check from the drivers, except from i915, because this doesn't work for the legacy tiling->modifier path. Adding the check to framebuffer_check() will guarantee that the igt@kms_addfb_basic@addfb25-bad-modifier IGT test passes, showing the correct behavior of the check. This patchset was tested on amdgpu and vc4 with the IGT tests.
