commit: 82d9d54a6c0ee8b12211fa4e59fd940a2da4e063 ALSA: hda: add Intel DSP configuration / probe code
date:   2 months ago
config: alpha-randconfig-a001-20200101 (attached as .config)
compiler: alpha-linux-gcc (GCC) 7.5.0
reproduce:
        wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout 82d9d54a6c0ee8b12211fa4e59fd940a2da4e063
        # save the attached .config to linux build tree
        GCC_VERSION=7.5.0 make.cross ARCH=alpha
