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

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.

I don't know if this is superseeded by something else but I found this
while trying to use the connector from msm_dsi in this function.
