Hi Greg,
The following lt9611uxc fixes in v5.15.139 broke display on RB5 devboard.
drm/bridge: lt9611uxc: fix the race in the error path
drm/bridge: lt9611uxc: Register and attach our DSI device at probe
drm/bridge: lt9611uxc: Switch to devm MIPI-DSI helpers
Reverting them (git revert -s d0d01bb4a560 29aba28ea195 f53a04579328
#5.15 SHA Ids) fix the following errors on RB5 and get the display
working again on v5.15.143.
lt9611uxc 5-002b: LT9611 revision: 0x17.04.93
lt9611uxc 5-002b: LT9611 version: 0x43
lt9611uxc 5-002b: failed to find dsi host
msm ae00000.mdss: bound ae01000.mdp (ops dpu_ops [msm])
msm_dsi_manager_register: failed to register mipi dsi host for DSI 0: -517
Regards,
Amit Pundir

Great, can you send patches that do the reverts along with the reasoning
why the reverts are needed so that we can queue them up?
thanks,
