First of all,the address of pdev->dev is assigned to mop500_card.dev,
then the function platform_set_drvdata copies the value the variable
card to pdev->dev.driver_data,but when calling snd_soc_register_card,
the function dev_set_drvdata(card->dev, card) will also do the same
copy operation,so i think that the former copy operation can be removed.

This reverts commit f1013cdeee ("ASoC: ux500: drop platform DAI
assignments"), which seems to have been based on a misunderstanding and
prevents the platform driver callbacks from being made (e.g. to
preallocate DMA memory).
The real culprit for the warnings about attempts to create duplicate
procfs entries was commit 99b04f4c40 ("ASoC: add Component level
pcm_new/pcm_free" that broke PCM creation on systems that use more than
one platform component.

This platform is completely probed by device tree nowadays, so
we need to do a bigger cleanup removing all the non-DT codepaths.
This cleanup must however go in as a fix since it fixes a
regression.
Currently when Ux500 audio is enabled, dmesg complains like
this:
entry->name == "prealloc"
entry->name == "prealloc_max"
entry->name == "prealloc"

This is because PCMs are created twice for the same hardware,
and this happens because both "platform" and "CPU" DAI links
are specified.
But platform/CPU is an either/or pair, not a both/and pair.
This has maybe worked in the past, but it is causing trouble
now, so let us begin the cleanups by removing the platform
assignment and silencing the boot noise, and make a proper DT
cleanup for the next kernel cycle.

Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes, just
removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There are
some ath9k patches coming in through this tree that have been acked by
the wireless maintainers as they relied on the debugfs changes.
Everything has been in linux-next for a while.

We're getting closer to fully enabling the Ux500 ASoC driver for Device

by only Device Tree nodes. In this patch we NULL out the platform_name,
and supply nodes for each platform device.

The PCM is a pseudo-device. It doesn't have any of it's own registers
or hardware. It rather acts as a layer of abstraction for DMA
transfers. Hence, instead of classifying it as a device in its own
right, we call the initialisation from the MSP driver.
