I'm sorry, I should've waited for my test results first.  Looks like
this patch alone is insufficient.  Looking at 5.15 stable branch, I see
that we probably need:

    ASoC: Intel: bxt_da7219_max98357a: shrink platform_id below 20 characters
    ASoC: Intel: sof_rt5682: shrink platform_id names below 20 characters
    ASoC: Intel: glk_rt5682_max98357a: shrink platform_id below 20 characters
    ASoC: Intel: kbl_da7219_max98357a: shrink platform_id below 20 characters
    ASoC: Intel: sof_da7219_max98373: shrink platform_id below 20 characters
    ASoC: Intel: sof_da7219_mx98360a: fail to initialize soundcard
    ASoC: Intel: Fix platform ID matching

Unless I'm mistaken, the firt series are part of the merge commit
98c69fcc9f5902b0c340acdbbfa365464efc52d2.  The followup fixes are:

    0f32d9eb38c13c32895b5bf695eac639cee02d6c
    f4eeaed04e861b95f1f2c911263f2fcaa959c078

I didn't find anything else that seemed obviously elevant, but I didn't
dug deep.  With these backports, I can build 5.10.241 fine -- but I
don't have any hardware to test these drivers.
