[PATCH v3 00/14] ASoC: tegra: Add error logging for probe and callback failures

[PATCH v3 00/14] ASoC: tegra: Add error logging for probe and callback failures

[Sheetal]

Log errors in probe and runtime error paths across Tegra audio drivers.
Use dev_err_probe() in probe paths and dev_err() in runtime callbacks.
Skip redundant logging where the underlying API already reports errors.

Changes in v3:
- Split single patch into per-driver patch series for easier review
  and incremental merging.
- Drop dev_err() from tegra_ahub_put_value_enum() since the error path
  is userspace-triggerable and would allow log spamming.
- Drop dev_err() from tegra210_mixer_set_audio_cif() since the driver
  advertises S8 format support but this function doesn't handle it,
  creating a userspace-triggerable log spam path.

Changes in v2:
- Use dev_err_probe() in all probe error paths as a defensive measure,
  instead of only where -EPROBE_DEFER is currently known to be returned.
- Drop redundant error logging for devm_platform_ioremap_resource() and
  devm_ioremap_resource() since these APIs already log errors internally.

[14/14] ASoC: tegra: Use dev_err_probe() in tegra_audio_graph_card probe
        https://git.kernel.org/broonie/sound/c/f7d9eb0291ef

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
