Subject: [CFT 04/31] dmaengine: PL08x: remove circular_buffer boolean from channel data

From: [email-masked] (Russell King)
Date: Thu, 07 Jun 2012 11:47:02 +0100

Circular buffers are not handled in this way; we have a separate API
call now to setup circular buffers.  So lets not mislead people with
this bool.
