Changes from v3: - [1/3]: the code now checks (connector->dev) instead of (!!panel_bridge->connector.dev) - [2/3]: the macro is now called drmm_plain_encoder_alloc(), and moved to . It also takes funcs/name parameters to be more similar to drmm_encoder_alloc(), although these parameters can very well be NULL. - [3/3] uses the new macro. V3 had a 4th patch, which was already applied as it received a reviewed-by tag and could be applied independently.
