From 02b16fbc56e97b295239c83e43f186c191e42dd3 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Wed, 29 Jun 2022 12:27:46 +0300 Subject: [PATCH] drm/edid: move drm_connector_update_edid_property() to drm_edid.c MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The function needs access to drm_edid.c internals more than drm_connector.c. We can make drm_reset_display_info(), drm_add_display_info() and drm_update_tile_info() static. There will be more benefits with follow-up struct drm_edid refactoring.
