Subject: [PATCH 5.15 076/189] drm/msm/dsi: Use connector directly in msm_dsi_manager_connector_init()

From: Stephen Boyd <swboyd@...omium.org>

[ 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.
