Subject: Re: [PATCH v3] drm: of: Properly try all possible cases for bridge/panel detection

Hi Paul,

This patch breaks the ingenic-drm driver.

It calls drm_of_find_panel_or_bridge(np, 0, i, ...) starting for i=0, until
-ENODEV is returned, which does not happen anymore.

The idea is to probe all the connected panels/bridges, should it be done
differently now?

Cheers,
-Paul
