From 5fb908ebb875c1332f6a24cc536782f2a843ec00 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 5 Feb 2020 20:35:43 +0200 Subject: [PATCH] drm/i915: Mark all HPD capabled connectors as such MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently we only set the DRM_CONNECTOR_POLL_{DISCONNECT,CONNECT} bits in intel_connector->polled (the base setting), leading to some confusing looking code to reset drm_connector->polled (the actual setting) to DRM_CONNECTOR_POLL_HPD. Let's set intel_connector->polled = DRM_CONNECTOR_POLL_HPD for all hpd capable connectors, and then we don't need so many special cases in the hotplug code.
