From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

Refactor the code responsible for selecting the correct device node for
audio endpoint parsing in the rsnd driver. A new helper function
`rsnd_pick_endpoint_node_for_ports()` is introduced to handle the
selection of the endpoint node by checking whether the port is named
'port' or 'ports'.

This change simplifies the logic in both `rsnd_dai_of_node()` and
`rsnd_dai_probe()` functions by replacing repetitive condition checks
with the new helper.

Thanks!

[1/1] ASoC: rsnd: Refactor port handling with helper for endpoint node selection
      commit: daf5e3c68144bdb7e605f46853febc7bb257d44d

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
