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

From: Maxime Ripard
Date: Thu Oct 16 2014 - 06:38:51 EST


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.
