Now snd_ac97_bus() takes the const ops pointer, so we can define the
snd_ac97_bus_ops locally as const as well for further optimization.
There should be no functional changes by this patch.

PCM core deals the empty ioctl field now as default(*).

Clean up the driver with the new managed buffer allocation API.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Updates for v4.14
This is quite a large release by volume of patches and diff, a lot of
that is mechanical cleanup patches but it's great to also see a range of
vendors actively working on adding new features and fixing issues in
their drivers. Intel and Realtek have been especially active here.
- Continued work towards moving everything to the component model from
Morimoto-san.
- Use of devres for jack detection GPIOs, eliminating some potential
resource leaks.
- Jack detection support for Qualcomm MSM8916.
- Support for Allwinner H3, Cirrus Logic CS43130, Intel Kabylake
systems with RT5663, Realtek RT274, TI TLV320AIC32x6 and Wolfson
WM8523.

platform_get_irq() returns an error code, but the ac97c
driver ignores it and always returns -ENXIO. This is not correct,
and prevents -EPROBE_DEFER from being propagated properly.

Print and propagate the return value of platform_get_irq on failure.

Treat both negative and zero return values from clk_round_rate()
as errors. This is needed since subsequent patches will convert
clk_round_rate()'s return value to be an unsigned type, rather
than a signed type, since some clock sources can generate rates higher
than (2^31)-1 Hz.
Eventually, when calling clk_round_rate(), only a return value of
zero will be considered a error; all other values will be
considered valid rates. The comparison against values less than
0 is kept to preserve the correct behavior in the meantime.
