From 04770b082e2a207804c633fbfd5efec28cbc5673 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jouni=20H=C3=B6gander?= Date: Fri, 10 Jun 2022 11:54:28 +0300 Subject: [PATCH] drm/i915: Do not start connector polling if display is disabled MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently we are starting connector polling if display is disabled using disable_display module parameter. Polling is just returning always "not connected" state. This can be optimized by not starting polling at all.
