[PATCH] ASoC: sdw_utils: fix missing component_name for cs42l43 part_id 0x2A3B

[Chia-Lin Kao (AceLan)]

commit 87a3f5c8ac20 ("ASoC: sdw_utils: cs42l43: allow spk component names
to be combined") moved spk:cs42l43-spk generation from rtd_init() into
the asoc_sdw_rtd_init() generic path by adding component_name to
codec_info_list entries. However, only the 0x4243 cs42l43 entry was
updated; the 0x2A3B entry (vendor_id 0x01fa, Cirrus Logic cs42l43 with
sidecar bridge) was missed.

Without component_name on the 0x2A3B dp6 DAI, asoc_sdw_rtd_init() never
accumulates spk_components and never appends 'spk:cs42l43-spk' (or its
sidecar alias 'spk:cs35l56-bridge') to card->components. The sof-soundwire
UCM regex ' spk:([a-z0-9]+...)' then fails to match, causing WirePlumber
to mark all HiFi profiles as unavailable=no and fall back to the Off
profile — resulting in Dummy Output in GNOME.

The existing sidecar redirect in asoc_sdw_rtd_init() already handles the
SOC_SDW_SIDECAR_AMPS case: when component_name is 'cs42l43-spk' and
sidecar amps are active, it substitutes 'cs35l56-bridge' into
card->components, which matches the existing cs35l56-bridge.conf UCM file.

Thanks!

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

Hi Chia-Lin Kao,

Did you get a bounce email for this patch from the Cirrus folks
and if so can I get a copy of that?

It seems we are all on it but none of us received the email. I am
assuming something went wrong in our email stack but if there was
a bounce would be excellent to have something to point our IT
people at.

Thanks,
Charles
