when are those parameters saved...

... since there's nothing done on suspend?

Also there's something weird here since the patch enables pm_runtime but
there's nothing related to pm_runtime here, i.e. SET_RUNTIME_PM_OPS()
is missing.

We are saving adata in acp_i2s_hwparams 
<https://elixir.bootlin.com/linux/v6.7-rc1/C/ident/acp_i2s_hwparams> and 
acp_i2s_set_tdm_slot,

These are the parameters saving in adata struct tdm_tx_fmt, tdm_rx_fmt,
lrclk_div and bclk_div.

runtime pm ops are not required as this is a dma driver.

Linux regression tracking (Thorsten Leemhuis) Dec. 15, 2023, 11:14 a.m. UTC | #3
Hi, Thorsten here, the Linux kernel's regression tracker. Top-posting
for once, to make this easily accessible to everyone.

Does anyone know what happened to below patch? It afaics was meant to
fix a regression that made it into 6.6. For details see:

https://lore.kernel.org/lkml/87a5v8szhc.fsf@mutex.one/
https://lore.kernel.org/lkml/ac9d4f7b-c7af-4d21-b0b8-d0f188b94b0f@amd.com/

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
