url: https://github.com/0day-ci/linux/commits/Akshu-Agrawal/ASoC-AMD-make-channel-1-dma-as-circular/20180527-170008
base: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next
config: x86_64-randconfig-x014-201821 (attached as .config)
compiler: gcc-7 (Debian 7.3.0-16) 7.3.0
reproduce:
# save the attached .config to linux build tree
make ARCH=x86_64
