The UCM configuration for AMD ACP digital microphones combines HDA analog card
with ASoC AMD ACP digital microphone card. When the ACP microphone card
is detected later than HDA analog card, the UCM initialization for HDA
analog card should be executed again.
Additional changes:
Added --with-alsactl-udev-extra-test argument to handle the tests for
directories. The default value was kept.
Added --alsactl-udev-args argument to pass extra arguments to alsactl
in the udev rule.
Note: The autoconf does not handle correctly spaces so configure
call like 'configure --alsactl-udev-args="-E ENV=abcd"' is not allowed.
Substitue '__' string as ' ' for this reason.
Example:
configure --with-alsactl-udev-args="-E__ENV=abcd" \
--with-alsactl-udev-extra-test='TEST=="/abcd",__TEST=="/xyz",'
