From a5671bee6d6e9fc7cb87366acd0ed830779c3c33 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Mon, 20 Mar 2023 16:07:45 +0100 Subject: [PATCH] drm/fbdev-generic: Remove unused prefer_shadow_fbdev flag Remove the flag prefer_shadow_fbdev from struct drm_mode_config. Drivers set this flag to enable shadow buffering in the generic fbdev emulation. Such shadow buffering is now mandatory, so the flag is unused.
