[1/1] ASoC: dwc: don't assign addr_width for dt configs
Commit Message
For proper DMA operation addr_width must corresponds with audio format
(S16, S24, S32, etc). Proper bus width calculations is performed by
snd_hwparams_to_dma_slave_config(). So drop wrong addr_width asignment
for dt configs and let snd_hwparams_to_dma_slave_config() do the job.

[1/1] ASoC: dwc: don't assign addr_width for dt configs
commit: 6f80197f40515853814d0f22e5209d53f899ab91
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
