Mengdong Lin 5015920a17 ASoC: Vendor drivers get a link's runtime by snd_soc_get_pcm_runtime()
Vendor drivers no longer access a DAI link's runtime by the link index
but by matching the link name via snd_soc_get_pcm_runtime(). We assume
each DAI link has a unique name.

This is preparation for changing runtimes from an array to a list later.

Vendor drivers changed:
sound/soc/fsl/fsl-asoc-card.c
sound/soc/fsl/imx-wm8962.c
sound/soc/pxa/mioa701_wm9713.c

Dan Carpenter 474ff0ae23 ASoC: imx-wm8962: Add a missing error check
My static checker complains that:

	sound/soc/fsl/imx-wm8962.c:196 imx_wm8962_probe() warn:
	we tested 'ret' before and it was 'false'

The intent was that we use "ret" to check imx_audmux_v2_configure_port().

Fabio Estevam 0984f34100 ASoC: fsl: imx-wm8962: Set the card owner field
The following crash happens when trying to unload the snd_soc_imx_wm8962 module
while playback is active:

[  208.666868] Unable to handle kernel paging request at virtc
[  208.674110] pgd = 80004000
[  208.676867] [7f06541c] *pgd=4c334811, *pte=00000000, *ppte=00000000

[  208.688445] Modules linked in: snd_soc_wm8962 snd_soc_fsl_ssi snd_soc_imx_audmux imx_pcm_fiq evbug]
...

In order to avoid such problem, fill the card owner field as suggested by
Lars-Peter Clausen:

"But looking at the source it seems that this is a core feature of ALSA and at
least for the card module itself it will do the ref-counting when a stream is
started/stopped. And we even support setting the owner of a card in ASoC.
It's just that pretty much no ASoC card driver bothers to set the owner field
in the snd_soc_card struct. So this particular problem can be fixed by updating
the imx-wm8962 driver to set the owner field."

By doing as suggested, we no longer see the crash when attempting to unload the
snd_soc_imx_wm8962 module while playback is active:

$ modprobe -r snd_soc_imx_wm8962
modprobe: can't unload module snd_soc_imx_wm8962: Resource temporarily

Linus Torvalds e6b5be2be4 Driver core patches for 3.19-rc1
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.

Shawn Guo 47cf84e17e ASoC: fsl: fix pm support of machine drivers
The commit 1abe729 (ASoC: fsl: Add missing pm to current machine
drivers) enables pm support for a few IMX machine drivers.  But it does
not update dev drvdata to be the pointer to 'card'.  This causes the
kernel dump below in system suspend, because snd_soc_suspend() expects
that the dev drvdata points to 'card', while it still points to the
private data of machine driver.

This patch fixes imx-sgtl5000 and imx-wm8962 by attaching 'card' to dev
drvdata and private data to card drvdata.  For imx-mc13783, I simply
revert the pm change because it must be broken for the same reason and
I don't have hardware to test pm enabling code.

I2C of helpers used to live in of_i2c.c but experience (from SPI) shows
that it is much cleaner to have this in the core. This also removes a
circular dependency between the helpers and the core, and so we can
finally register child nodes in the core instead of doing this manually
in each driver. So, fix the drivers and documentation, too.
