* d/p/0010-add-bios-version-for-looking-for-ucm.patch
Add a new way to looking for the ucm by DMI bios_version.
Without this patch, the alsa-lib looks for the ucm by cardlongname
first, if it fails, then by the cardname. This has a problem at least
on LENOVO machines, since a LENOVO model has the same audio design but
it has hundreds of cardlongname, we need to create hundreds of folders
for one model, that is unacceptable. LENOVO told us a LENOVO model has
the unique biso_version, we could use it to find the ucm. After applying
this patch, the alsa-lib looks for the ucm by cardlongname first, if it
fails, it will use bios_version, if it also fails, it will fallback to
cardname.
