From ca7b6b7176ffea4d07afbd98ede7a94fb0f68fa1 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 26 May 2020 04:14:58 +0300 Subject: [PATCH] drm: bridge: dw-hdmi: Store current connector in struct dw_hdmi Store the connector that the bridge is currently wired to in the dw_hdmi structure. This is currently identical to the connector field, but will differ once the driver supports disabling connector creation.
