2014-12-22dmaengine: Add a warning for drivers not using the generic slave caps retrievalMaxime Ripard
For the slave caps retrieval to be really useful, most drivers need to implement it. Hence, we need to be slightly more aggressive, and trigger a warning at registration time for drivers that don't fill their caps infos in order to encourage them to implement it.
