Guys, any reason to keep me, the author of the driver, out of loop ?
I almost lost this patch, had it not for chance.

Also, I noticed
42bc9cf45939c2   'DMA: PL330: Add DMA_CYCLIC capability'
while implements my correction, doesn't carry the ack
 http://www.spinics.net/lists/linux-samsung-soc/msg06386.html

While, unlike some, I am not interested in claiming territory by pissing
around acks, I would sure like to log my acks if I spent personal time
maintaining the code I am supposed to be responsible for.
