2dc1158137 of/device: Replace struct of_device with struct platform_device
of_device is just an alias for platform_device, so remove it entirely.  Also
replace to_of_device() with to_platform_device() and update comment blocks.

This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.

b9033e682e dma: dmatest: fix potential sign bug
'cnt' is unsigned, so this code may become wrong in future as
dmatest_add_threads() can return error code:

	cnt = dmatest_add_threads(dtc, DMA_MEMCPY);
	thread_count += cnt > 0 ? cnt : 0;
		        ^^^^^^^

Now it can return only -EINVAL if and only if second argument of
dmatest_add_threads() is not one of DMA_MEMCPY, DMA_XOR, DMA_PQ.
So, now it is not wrong but may become wrong in future.

The semantic patch that finds this problem (many false-positive results):

556ab45f9a ioat2: catch and recover from broken vtd configurations v6
On some platforms (MacPro3,1) the BIOS assigns the ioatdma device to the
incorrect iommu causing faults when the driver initializes.  Add a quirk
to catch this misconfiguration and try falling back to untranslated
operation (which works in the MacPro3,1 case).

Assuming there are other platforms with misconfigured iommus teach the
ioatdma driver to treat initialization failures as non-fatal (just fail
the driver load and emit a warning instead of triggering a BUG_ON).

This can be classified as a boot regression since 2.6.32 on affected
platforms since the ioatdma module did not autoload prior to that
kernel.

channels are strictly for device to host or host to device

This patch add DMA drivers for DMA controllers in Langwell chipset
of Intel(R) Moorestown platform and DMA controllers in Penwell of
Intel(R) Medfield platfrom

This patch adds support for Moorestown DMAC1 and DMAC2 controllers.
It also add support for Medfiled GP DMA and DMAC1 controllers.
These controllers supports memory to peripheral and peripheral to
memory transfers. It support only single block transfers.

This driver is based on Kernel DMA engine
Anyone who wishes to use this controller should use DMA engine APIs

This controller exposes DMA_SLAVE capabilities and notifies the client drivers
of DMA transaction completion

Config option required to be enabled CONFIG_INTEL_MID_DMAC=y

4018294b53 of: Remove duplicate fields from of_platform_driver
.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver.  This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.

This patch is a pretty mechanical change.  The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial.  This patch looks big and scary because it touches so
many files, but it should be pretty safe.
