From 5343f29b3dc534be01b45cd3a3e43572996f96f8 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Tue, 2 Jan 2024 13:21:58 +0100 Subject: drm: Move drm_set_preferred_mode() helper from drm_edid to drm_modes The helper is generic, it doesn't use the opaque EDID type struct drm_edid and is also used by drivers that only support non-probeable displays such as fixed panels. These drivers add a list of modes using drm_mode_probed_add() and then set a preferred mode using the drm_set_preferred_mode() helper. It seems more logical to have the helper definition in drm_modes.o instead of drm_edid.o, since the former contains modes helper while the latter has helpers to manage the EDID information. Since both drm_edid.o and drm_modes.o object files are built-in the drm.o object, there are no functional changes. But besides being a more logical place for this helper, it could also allow to eventually make drm_edid.o optional and not included in drm.o if only fixed panels must be supported in a given system.
