Subject: [PATCH 2/3] drm: Remove references to removed transitional helpers
The transitional helpers were removed a long time ago, but some
references stuck. Remove them.
Fixes: 21ebe615c16994f3 ("drm: Remove transitional helpers")
Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>
---
It doesn't look like the drm_encoder_helper_funcs were ever used by the
transitional plane helpers?
