[PATCH v2 02/53] dmaengine: Make channel allocation callbacks optional

From: Maxime Ripard <hidden>
Date: 2014-10-16 10:38:48
Also in: lkml
Subsystem: dma generic offload engine subsystem, the rest · Maintainers: Vinod Koul, Linus Torvalds

Nowadays, some drivers don't have anything in there channel allocation
callbacks anymore.

Remove the BUG_ON if those callbacks aren't implemented, in order to allow
drivers to not implement them.
