From 6398e4d4ca0ad41feed529aa95c96a12d78f6124 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Wed, 6 Sep 2023 11:12:26 -0700 Subject: [PATCH] drm/msm/dp: Remove error message when downstream port not connected Plugging in an Apple dongle without the HDMI cable attached prints out an error message in the kernel logs when nothing is actually wrong. no downstream ports connected This is because the downstream port for the HDMI connector is not connected, so the Apple dongle reports that as a zero sink count device.
