In the individual case, maybe. However, assuming codec vendor and
subsystem are correctly matched, a distro could make a long list of
Codec SSID to model mappings, write down that in the patch file format,
and supply that patch file. One could then add mappings as a minor
distro update without having to recompile the kernel.
