I have a limited understanding of all this, but we already support the 
machine drivers as modules and things work fine.

I wonder if this MODULE_DEVICE_TABLE generates the alias automatically, 
which would make the existing ones added manually at the end of the 
files unnecessary? If that was the case, then we should remove those 
MODULE_ALIAS as well, no?

MODULE_DESCRIPTION("SOF Audio Machine driver");
MODULE_AUTHOR("Bard Liao <bard.liao at intel.com>");
MODULE_AUTHOR("Sathya Prakash M R <sathya.prakash.m.r at intel.com>");
MODULE_AUTHOR("Brent Lu <brent.lu at intel.com>");
MODULE_LICENSE("GPL v2");
MODULE_ALIAS("platform:sof_rt5682");
MODULE_ALIAS("platform:tgl_max98357a_rt5682");
MODULE_ALIAS("platform:jsl_rt5682_rt1015");
MODULE_ALIAS("platform:tgl_max98373_rt5682");
MODULE_ALIAS("platform:jsl_rt5682_max98360a");
MODULE_ALIAS("platform:cml_rt1015_rt5682");
MODULE_ALIAS("platform:tgl_rt1011_rt5682");
MODULE_ALIAS("platform:jsl_rt5682_rt1015p");
