[PATCH v2 01/12] drm/bridge: megachips-stdpxxxx-ge-b850v3-fw: don't select unused DRM_PANEL

[Luca Ceresoli]

This driver does not use the drm_panel APIs at all, so no need to select
DRM_PANEL.

Looks right to me. Ages ago it used panel APIs directly, but not today.

Which exact "drm_panel_bridge" API does it use? I don't see any...
Certainly it's highly likely that the next bridge in the chain is a
panel, but there are no API calls that I see. Maybe the scripts got
confused because the variable name didn't get updated in commit
5486eac81004 ("drm/bridge: parade-ps8640: switch to
devm_drm_of_get_bridge") ?
