[PATCH][next] ASoC: Intel: Skylake: Avoid the use of one-element array

[Gustavo A. R. Silva]

One-element arrays are being deprecated[1]. Replace the one-element
array with a simple value type 'u8 reserved'[2], once it seems this
is just a placeholder for alignment.

Looks ok and tests on our side also pass.

[1/1] ASoC: Intel: Skylake: Avoid the use of one-element array
      commit: 23f8d964f15a21991a166f0d1a7cf3cf8e4bfc9b

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
