To avoid this move the panel's first DSI access to enable() so the upstream bridge can prepare the DSI host controller in it's pre_enable(). The second patch makes the disable() call symmetric to the above and the third one just eases debugging. Changes from v1: * As per review comments by Sam Ravnborg * Ignore failures to disable the backlight in jh057n_disable() * Add 'drm/panel: jh057n00900: Use drm_panel_{unprepare,disable} consistently' * Collected Reviewed-By: Thanks Sam!
