Check for snd_soc_ops structures that are only stored in the ops field of a
snd_soc_dai_link structure. This field is declared const, so snd_soc_ops
structures that have this property can be declared as const also.

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.

According to the sgtl5000 datasheet the MCLK frequency range restriction of
8 to 27 MHz only applies when the PLL is used - synchronous SYS_MCLK input mode.
mxs-sgtl5000 machine sets the codec as slave, and mx28 generates MCLK in the
range of 256*fs, 384*fs or 512*fs, which is called asynchronous SYS_MCLK
input.
In asynchronous SYS_MCLK we cannot have the 8 to 27 MHz check because if we
want to play a 8KHz sample rate track, with a MCLK of 8k * 512 = 4.096MHz the
current check would return -EINVAL, which is not correct.
Remove the 8 to 27MHz frequency check, since this only applies to the
synchronous SYS_MCLK input case.

On a mx28 board, running "aplay -l" and "arecord -l" results in the following:
$ aplay -l
**** List of PLAYBACK Hardware Devices ****

Subdevices: 1/1

card 0: mxssgtl5000 [mxs_sgtl5000], device 1: Capture sgtl5000-1 []
Subdevices: 1/1
Subdevice #0: subdevice #0
,which is not correct because we got a capture device listed in aplay and a
playback device listed in arecord.
On mx28 there are two serial audio interface ports (SAIF0 and SAIF1) and each
one of them are unidirectional.
Allow to specify a dai link as 'playback_only' or 'capture_only', which suits
well for this case.
After this change we can correctly report the capabilities as follows:
$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: mxssgtl5000 [mxs_sgtl5000], device 0: HiFi Playback sgtl5000-0 []

It makes no sense to hardcode the I2C bus into the codec_name field.
cpu_dai_name and platform_name are also overwritten later in
mxs_sgtl5000_probe_dt().
So remove the three fields, as mxs platform is dt-only platform.

Prior to this patch, the CPU side of a DAI link was specified using a
single name. Often, this was the result of calling dev_name() on the
device providing the DAI, but in the case of a CPU DAI driver that
provided multiple DAIs, it needed to mix together both the device name
and some device-relative name, in order to form a single globally unique
name.
However, the CODEC side of the DAI link was specified using separate
fields for device (name or OF node) and device-relative DAI name.
This patch allows the CPU side of a DAI link to be specified in the same
way as the CODEC side, separating concepts of device and device-relative
DAI name.
I believe this will be important in multi-codec and/or dynamic PCM
scenarios, where a single CPU driver provides multiple DAIs, while also
booting using device tree, with accompanying desire not to hard-code the
CPU side device's name into the original .cpu_dai_name field.
Ideally, both the CPU DAI and CODEC DAI loops in soc_bind_dai_link()
would now be identical. However, two things prevent that at present:
1) The need to save rtd->codec for the CODEC side, which means we have
to search for the CODEC explicitly, and not just the CODEC side DAI.
2) Since we know the CODEC side DAI is part of a codec, and not just
a standalone DAI, it's slightly more efficient to convert .codec_name/
.codec_of_node into a codec first, and then compare each DAI's .codec
field, since this avoids strcmp() on each DAI's CODEC's name within
the loop.
However, the two loops are essentially semantically equivalent.
