[PATCH] ASoC: constify of_phandle_args in snd_soc_get_dai_name()
The pointer to of_phandle_args passed to snd_soc_get_dai_name() and of_xlate_dai_name() implementations is not modified. Since it is being used only to translate passed OF node to a DAI name, it should not be modified, so mark it as const for correctness and safer code.

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
