The maximum name length for a platform_device_id entry is 20 characters
including the trailing NUL byte. The sof_nau8825.c file exceeds that,
which causes an obscure error message:

sound/soc/intel/boards/snd-soc-sof_nau8825.mod.c:35:45: error: illegal character encoding in string literal [-Werror,-Winvalid-source-encoding]
MODULE_ALIAS("platform:adl_max98373_nau8825<U+0018><AA>");
                                                   ^~~~
include/linux/module.h:168:49: note: expanded from macro 'MODULE_ALIAS'
                                                ^~~~~~
include/linux/module.h:165:56: note: expanded from macro 'MODULE_INFO'
                                                       ^~~~
include/linux/moduleparam.h:26:47: note: expanded from macro '__MODULE_INFO'
                = __MODULE_INFO_PREFIX __stringify(tag) "=" info

I could not figure out how to make the module handling robust enough
to handle this better, but as a quick fix, using slightly shorter
names that are still unique avoids the build issue.

Thanks Arnd, yes unfortunately that keeps on happening. We cleaned-up a
bunch of Chromebook platforms but newer ones have the same long name
issue obviously.

Thanks!

[1/1] ASoC: Intel: sof-nau8825: fix module alias overflow
      commit: 3e78986a840d59dd27e636eae3f52dc11125c835

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
