Hi Matt,
FYI, the error/warning still remains.
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master head: a188339ca5a396acc588e5851ed7e19f66b0ebd9 commit: 7df95299b94a63ec67a6389fc02dc25019a80ee8 staging: kpc2000: Add DMA driver date: 4 weeks ago config: xtensa-allmodconfig (attached as .config) compiler: xtensa-linux-gcc (GCC) 8.1.0 reproduce: wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross chmod +x ~/bin/make.cross git checkout 7df95299b94a63ec67a6389fc02dc25019a80ee8 # save the attached .config to linux build tree GCC_VERSION=8.1.0 make.cross ARCH=xtensa
