Commit Message

Boris Brezillon Aug. 26, 2019, 3:26 p.m. UTC
Change the prefix of bridge helpers targeting a bridge chain from
drm_bridge_ to drm_bridge_chain_ to better reflect the fact that
the operation will happen on all elements of chain, starting at the
bridge passed in argument.

Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com>
---
Changes in v2:
* Pass te bridge, not the encoder, so we can later act on a sub-chain
  instead of the whole chain
