This is a note to let you know that I've just added the patch titled drm/msm/dsi: Use connector directly in msm_dsi_manager_connector_init() to the 5.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: drm-msm-dsi-use-connector-directly-in-msm_dsi_manage.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit b2ff2b043064cd521caf7dc0158398824997115b Author: Stephen Boyd <swboyd@xxxxxxxxxxxx> Date: Thu Mar 17 17:07:31 2022 -0700 drm/msm/dsi: Use connector directly in msm_dsi_manager_connector_init() [ Upstream commit 47b7de6b88b962ef339a2427a023d2a23d161654 ] The member 'msm_dsi->connector' isn't assigned until msm_dsi_manager_connector_init() returns (see msm_dsi_modeset_init() and how it assigns the return value). Therefore this pointer is going to be NULL here. Let's use 'connector' which is what was intended.
