The lack of comma leads to the wrong channel for an SPDIF channel.
Unfortunately this wasn't caught by compiler because it's still a

This motherboard seems to have a flaky jack detection - when the
front HP is not present, the jack state quickly switches on and off.

This has been reported by three people in the bug, so I doubt it's
a user error this time.

ASoC: Updates  for v3.14

Not a lot going on framework wise, partly due to Christmas at least in
the case of the work I've been doing, but there's been quite a lot of
cleanup activity going on and the usual trickle of new drivers:

 - Update to the generic DMA code to support deferred probe and managed
   resources.
 - New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
   and Analog Devices AXI I2S and S/PDIF controller IPs.
 - Device tree support for the simple card, max98090 and cs42l52.
 - Conversion of the Samsung drivers to native dmaengine, making them
   multiplatform compatible and hopefully helping keep them more modern
   and up to date.
 - More regmap conversions, including a very welcome one for twl6040
   from Peter Ujfalusi.
 - A big overhaul of the DaVinci drivers also from Peter Ujfalusi.

This is a quick fix for the below two issues when building spdif as modules.

1) If modprobing modules in order: (Step 1) snd-soc-fsl-spdif -> (Step 2)
snd-soc-imx-spdif -> (Step 3) snd-soc-spdif-tx/rx, we will fail to create
imx-spdif card and dai link unless we rmmod snd-soc-imx-spdif and modprobe
it again due to the execution platform_driver_unregister() in probe() when
meeting -EPROBE_DEFER at Step 2.

2) After "imx-spdif sound-spdif.17: dit-hifi <-> 2004000.spdif mapping ok",
'rmmod snd-soc-imx-spdif' would cause kernel dump with warning:
WARNING: CPU: 0 PID: 1301 at /home/rmk/git/linux-rmk/fs/sysfs/dir.c:915 sysfs_hash_and_remove+0x84/0x90()
sysfs: can not remove 'dapm_widget', no directory
This should be caused by disordered resourse releasing of the whole link.
And trying to unregister the card and then CODEC dev can't fix this issue.

Thus this patch just provides a simple fix to these two bugs by using the
snd-soc-dummy in the core instead of seperate snd-soc-spdif-tx/rx so that
there's no need to handle the registering and unregistering of CODEC or
CODEC dai any more.

This patch adds SRC support to Renesas sound driver.

Renesas sound has SRC (= Sampling Rate Converter),
but, the HW implementation depends on its generation.
It was part of SRU on Gen1, and SCU on Gen2.
This SCU needs DMA transfer to use it.
Current rsnd driver is using it as DMA transfer buffer
(= no rate convert), and Gen1 is only supported at this point.

This patch cleanup it with focusing about SRC and Gen2 part.

ssi clock which is calculated from rsnd_ssi_master_clk_start()

SRC (= Sampling Rate Converter).
