[PATCH] ASoC: qcom: sdm845: only setup slim ports once

[Srinivas Kandagatla]

Currently same slim channel map setup for every dai link, which is redundant.
Fix this by adding a flag and conditionally setting these channel maps.

Thanks!

[1/1] ASoC: qcom: sdm845: only setup slim ports once
      commit: 5f55c9693a222ee1b8ec62a57fbcff59af0c4837

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
