[PATCH v2 0/5] ASoC: Harden DAPM route checks and Intel fixes

[PATCH v2 0/5] ASoC: Harden DAPM route checks and Intel fixes

[Cezary Rojewski]

Set of loosely connected patches. Most impactful change is dropping any
permisiveness when snd_soc_dapm_add_routes() fails in soc-topology.c To
do it safely, disable route checks for all skylake-driver boards.

Relevant background:

Since commit daa480bde6b3 ("ASoC: soc-core: tidyup for
snd_soc_dapm_add_routes()") route checks are no longer permissive. Probe
failures for Intel boards have been partially addressed by commit
a22ae72b86a4 ("ASoC: soc-core: isable route checks for legacy devices")
and its follow up but only skl_nau88l25_ssm4567.c is patched. The rest
of the boards still need fixing.

After that, removal of copy-pastas found in ssm4567.c and redundant code
in i2s_test.c for avs-boards.

Changes in v2:
- glk_rt5682_max98357a.c and skl_hda_dsp_generic.c now disable route
  checks only for the skylake-drvier
- asoc now logs failures of snd_soc_dapm_add_routes() in soc-topology.c

[PATCH v2 1/5] ASoC: Intel: Disable route checks for Skylake boards

[Cezary Rojewski]

Topology files that are propagated to the world and utilized by the
skylake-driver carry shortcomings in their SectionGraphs.

Since commit daa480bde6b3 ("ASoC: soc-core: tidyup for
snd_soc_dapm_add_routes()") route checks are no longer permissive. Probe
failures for Intel boards have been partially addressed by commit
a22ae72b86a4 ("ASoC: soc-core: disable route checks for legacy devices")
and its follow up but only skl_nau88l25_ssm4567.c is patched. Fix the
problem for the rest of the boards.

Fixes: daa480bde6b3 ("ASoC: soc-core: tidyup for snd_soc_dapm_add_routes()")

[PATCH v2 2/5] ASoC: topology: Do not ignore route checks when parsing graphs

[Cezary Rojewski]

One of the framework responsibilities is to ensure that the enumerated
DPCMs are valid i.e.: a valid BE is connected to a valid FE DAI. While
the are checks in soc-core.c and soc-pcm.c that verify this, a component
driver may attempt to workaround this by loading an invalid graph
through the topology file.

Be strict and fail topology loading when invalid graph is encountered.

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
