Hi Morimoto-san,

Please see the bisection report below about the asoc-simple-card
driver failing to probe on kontron-sl28-var3-ads2 in today's
broonie-sound tree.  I believe this has not reached linux-next
yet.

Reports aren't automatically sent to the public while we're
trialing new bisection features on kernelci.org but this one
looks valid.

Here's the full boot log:

  https://storage.kernelci.org/broonie-sound/for-next/v5.12-rc8-542-g80e0ab4291498/arm64/defconfig/gcc-8/lab-kontron/baseline-kontron-sl28-var3-ads2.html

More details can be found here:

  https://linux.kernelci.org/test/case/id/608089974135ccea439b779c/

Please let us know if you need any help debugging the issue or to
try a fix.

Best wishes,
Guillaume
