Subject: alsa: add ALSA_DEVICE_ID variable
X-Git-Url: http://gitweb.hugovil.com/?a=commitdiff_plain;h=e535318465cd474fde2fb6153b640fc2d626ef75;p=yocto%2Fmeta-hvmpd.git

alsa: add ALSA_DEVICE_ID variable

Note: asound.conf needs to be generated in alsa-state recipe. If not,
the following warniong will occur when creating the final image:

    check_data_file_clashes: Package alsa-utils wants to install file
    ...image-hvmpd-dev/1.0-r0/rootfs/etc/asound.conf
	But that file is already provided by package  * alsa-state
