Hi,

Fedora got a bug report[1] that sound was failing on Intel Bay Trail Socs
that use the MAX98090 module. I found

     ASoC: Intel: Load the atom DPCM driver only
     
     DPCM driver is recommended for BYT, CHT based platforms, so if
     CONFIG_SND_SST_IPC_ACPI is selected then don't compile the BYT
     Device IDs in common ACPI driver to avoid probe conflicts.

which changed the dependencies for CONFIG_SND_SOC_INTEL_BYT_MAX98090_MACH.
The set of options Fedora selects means that CONFIG_SND_SOC_INTEL_BYT_MAX98090_MACH
can't be selected. Is there another driver that's supposed to replace
CONFIG_SND_SOC_INTEL_BYT_MAX98090_MACH on Bay Trail or do the dependencies
need to be updated? The bugzilla has alsa-info for working and non-
working cases and the Fedora config is attached.

Thanks,
Laura
