[GIT PULL] dmaengine: one more driver for 2.6.36

[Dan Williams]

Hi Linus, please consider pulling from:

  git://git.kernel.org/pub/scm/linux/kernel/git/djbw/async_tx.git next

...to receive one more driver that was originally posted well in advance
of this window.  I had some review comments that were duly resolved, but
I did not handle this updated version in a timely manner.  I would
prefer that this driver not wait for 2.6.37 as it was prepared in time
for this window.  Two other fixlets are also included.

None of this has seen a -next release, but the driver passes my build
regression and the other two are obviously correct.

Thanks,
Dan

    DMAENGINE: driver for the ARM PL080/PL081 PrimeCells v4
    
    This creates a DMAengine driver for the ARM PL080/PL081 PrimeCells
    based on the implementation earlier submitted by Peter Pearse.
    This is working like a charm for memcpy and slave DMA to the PL011
    PrimeCell on the PB11MPCore.
    
    This DMA controller is used in mostly unmodified form in the ARM
    RealView and Versatile platforms, in the ST-Ericsson Nomadik, and
    in the ST SPEAr platform.
    
    It has been converted to use the header from the Samsung PL080
    derivate instead of its own defintions. The Samsungs have a custom
    driver in their mach-* folders though, atleast we can share the
    register definitions.

    DMAENGINE: correct PL080 register header file
    
    This PL008 among all other variables named PL080 doesn't seem
    right. Fix it. Also add some missing defined that I use in the
    new PL08x driver.

    Add a missing inline keyword for static function in linux/dmaengine.h to
    avoid duplicate symbol definitions.

    dma/shdma: move dereference below the NULL check
    
    "param" can be NULL here, so only dereference it after the check.
