Function drm_of_find_panel_or_bridge() is marked as deprecated: since
the usage of that in this driver exactly corresponds to the new function
devm_drm_of_get_bridge(), switch to it.

The original code doesn't print any log so it's probably fine, but
given you're already at it, perhaps you want to also make use of
dev_err_probe() here?
devm_drm_of_get_bridge() can also pass -EPROBE_DEFER from its wrapped
drm_of_find_panel_or_bridge(). Furthermore, that will make the code
visually align with your previous patch.
But that's just optional, and since this patch works anyway,

Thanks. Yeah it's a good idea to add an error print... since I will have

Cheers,
