[PATCH] ASoC: bt-sco: fix duplicate DAPM widget names for wideband DAI

[shengjiu.wang]

From: Shengjiu Wang <shengjiu.wang@nxp.com>

The bt-sco-pcm-wb DAI uses the same stream_name strings as bt-sco-pcm
("Playback" and "Capture"). This causes duplicate DAPM AIF widget
names within the same component, leading to debugfs warnings:

  debugfs: 'Playback' already exists in 'dapm'
  debugfs: 'Capture' already exists in 'dapm'

Give the wideband DAI distinct stream names ("WB Playback" and
"WB Capture") and add corresponding DAPM AIF widgets and routes for
them.

Fixes: 5947e1b4992e ("ASoC: bt-sco: extend rate and add a general compatible string")

Applied to

Thanks!

[1/1] ASoC: bt-sco: fix duplicate DAPM widget names for wideband DAI
      https://git.kernel.org/broonie/sound/c/0b604e886ece

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
