Applied "ASoC: fsl_ssi: AC'97 ops need regmap, clock and cleaning up on failure" to the asoc tree

[Mark Brown]

The patch

   ASoC: fsl_ssi: AC'97 ops need regmap, clock and cleaning up on failure

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] ASoC: fsl_ssi: AC'97 ops need regmap, clock and cleaning up
 on failure

AC'97 ops (register read / write) need SSI regmap and clock, so they have
to be set after them.

We also need to set these ops back to NULL if we fail the probe.
