ASoC: fsl-asoc-card: Don't add DAPM routes for ASRC if it doesn't exist

has been applied to the asoc tree at

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

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

There are a pair of warnings when ASRC is absent in the DTB: fsl-asoc-card sound: ASoC: no source widget found for ASRC-Playback fsl-asoc-card sound: ASoC: Failed to add route ASRC-Playback -> direct -> CPU-Playback fsl-asoc-card sound: ASoC: no sink widget found for ASRC-Capture fsl-asoc-card sound: ASoC: Failed to add route CPU-Capture -> direct -> ASRC-Capture

This is because the driver is still trying to add DAPM routes for ASRC even if it doesn't exist on that platform.

The warnings are harmless but it might be annoying. So this patch drops the DAPM routes of ASRC when it's absent in the DAI link.
