The snd_soc_dai_ops structures is only stored in the ops field of a
snd_soc_dai_driver structure, so make the snd_soc_dai_ops structure
const to allow the compiler to put it in read-only memory.

      commit: 3cab801e8b94280264ba23ab0683cd3a9c13ca9f

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
