ASoC: tracing: Export SND_SOC_DAPM_DIR_OUT to its value

The string SND_SOC_DAPM_DIR_OUT is printed in the snd_soc_dapm_path trace event instead of its value:

(((REC->path_dir) == SND_SOC_DAPM_DIR_OUT) ? "->" : "<-")

User space cannot parse this, as it has no idea what SND_SOC_DAPM_DIR_OUT is. Use TRACE_DEFINE_ENUM() to convert it to its value:

(((REC->path_dir) == 1) ? "->" : "<-")

So that user space tools, such as perf and trace-cmd, can parse it correctly.

      commit: 58300f8d6a48e58d1843199be743f819e2791ea3

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
