Hi all,

After merging the sound tree, today's linux-next build (powerpc
allyesconfig) failed like this:

sound/pci/hda/cs35l41_hda.c: In function 'cs35l41_get_acpi_sub_string':
sound/pci/hda/cs35l41_hda.c:693:43: error: invalid use of undefined type 'struct acpi_device'
  693 |         status = acpi_evaluate_object(adev->handle, "_SUB", NULL, &buffer);
      |                                           ^~

Caused by commit

  d60b05b4c780 ("ALSA: hda: cs35l41: Allow compilation test on non-ACPI configurations")

along with commit

  eef375960210 ("ALSA: hda: cs35l41: Support reading subsystem id from ACPI")

I have reverted commit d60b05b4c780 for today.
