[PATCH v2 2/2] drm/nouveau: vendor in drm_encoder_slave API

Dmitry Baryshkov
2024-12-15T10:19:36Z

Nouveau driver is the only user of the drm_encoder_slave API. Rework
necessary bits of drm_encoder_slave into the nouveau_i2c_encoder API and
drop drm_encoder_slave.c from the DRM KMS helper.

Suggested-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
