[PATCH v2 0/6] Raspberry Pi DMA fixes + cleanups

[Lukas Wunner <lukas@wunner.de>]

Two fixes and four cleanups for the Raspberry Pi DMA driver, v2.

Changes since v1:

* Patch [1/6]: Rework the patch to fix a race condition which could
  still occur with v1, and no longer check for idleness of a channel
  using the ACTIVE flag in the CS register (which is unreliable),
  but check for a zero control block address instead.

* Patch [2/6]: If outstanding writes fail to complete on abort of a
  transaction, print an error message and document a possible cause
  in a code comment. (Stefan Wahren)

* Patch [5/6] and [6/6]: Split patch to remove dead code in two and
  rephrase commit subject to be less generic. (Stefan Wahren, Vinod Koul)

Thanks,

Lukas
