If a ROM timeout is detected, we still stop the DMA but will return
the initial error should the DMA stop also fail.
Likewise the cleanup is handled regardless of the status, but we
return the initial error.

Such traces should be extremely rare but extremely useful for debug.
Report errors for all calls to sdn_sof_dsp_read_poll_timeout(), but
only on negative values for consistency.
Add traces that enable each timeout to be uniquely identified.

The patch
ASoC: SOF: Intel: hda: add dev_err() traces for snd_sof_dsp_read_poll_timeout()
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5
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

Subject: [PATCH] ASoC: SOF: Intel: hda-loader: improve error handling
If a ROM timeout is detected, we still stop the DMA but will return
the initial error should the DMA stop also fail.
Likewise the cleanup is handled regardless of the status, but we
return the initial error.
