From 7cdeb37c66e9b48fce8be9373bf5c96f2dd76c75 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 14 Dec 2017 21:30:50 +0100 Subject: [PATCH] drm/edid: kerneldoc for is_hdmi2_sink MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Also some breadcrumbs for how exactly to find this. Probably should pass drm_connector * or at least drm_display_info * to that function instead. But drm_hdmi_avi_infoframe_quant_range probably also wants drm_connector_state (and the hdmi stuff moved into that), so this is a bit more work. v2: Fix typo (Alex).
