From 9931e4be11f2129a20ffd908bc364598a63016f8 Mon Sep 17 00:00:00 2001 From: Antheas Kapenekakis Date: Fri, 29 Aug 2025 16:55:36 +0200 Subject: [PATCH 4960/5403] drm: panel-backlight-quirks: Make EDID match optional MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently, having a valid panel_id match is required to use the quirk system. For certain devices, we know that all SKUs need a certain quirk. Therefore, allow not specifying ident by only checking for a match if panel_id is non-zero.
