The only usage of these is to assign their address to the ops field in
the snd_soc_dai_driver struct, which is a pointer to const. Make them
const to allow the compiler to put them in read-only memory.

Thanks!

[1/1] ASoC: tegra: Constify static snd_soc_dai_ops structs
      commit: 313fab4820f3b1040bc1bd27cd4c7f69572951e8

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
