[PATCH 0/3] ASoC: SOF: couple of cleanups

[PATCH 0/3] ASoC: SOF: couple of cleanups

[Pierre-Louis Bossart]

Guennadi spotted inconsistencies with our 'const' handling, Ajit Kumar
flagged a missing check for a null pointer and we missed the
definition of debug zones.

This should be queued for 5.17.

Ajit Kumar Pandey (1):
  ASoC: SOF: ipc: Add null pointer check for substream->runtime

Guennadi Liakhovetski (1):
  ASoC: SOF: avoid casting "const" attribute away

Karol Trzcinski (1):

[PATCH 1/3] ASoC: SOF: avoid casting "const" attribute away

[Pierre-Louis Bossart]

From: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>

Casting "const" attribute away is dangerous, obtain a writable
pointer instead to avoid that.

[PATCH 2/3] ASoC: SOF: ipc: Add null pointer check for substream->runtime

[Pierre-Louis Bossart]

From: Ajit Kumar Pandey <AjitKumar.Pandey@amd.com>

When pcm stream is stopped "substream->runtime" pointer will be set
to NULL by ALSA core. In case host received an ipc msg from firmware
of type IPC_STREAM_POSITION after pcm stream is stopped, there will
be kernel NULL pointer exception in ipc_period_elapsed(). This patch
fixes it by adding NULL pointer check for "substream->runtime".

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
