Subject: [PATCH] dmaenginge.c: class_device_register() return value

Hi,

this patch makes dma_async_device_register() in drivers/dma/dmaengine.c
handle a failing class_device_register().  Patched against Linus' git
tree, compile-tested.

I also thought about calling dma_async_device_unregister on failure, but
I was not quite sure if this would work.  And I noticed that memory is
allocated for chan->local in dma_async_device_register() but I couldn't
find where it is released again.

I am quite new to this all, please give me feedback!
