Subjectinclude/linux/mlx5/driver.h:1299:13: error: 'struct irq_desc' has no member named 'affinity_hint'
Hi Israel,

FYI, the error/warning still remains.

tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 94d7dbf108813ea45a91e27e9a8bd231d5a23fa7
commit: 6082d9c9c94a408d7409b5f2e4e42ac9e8b16d0d net/mlx5: Fix mlx5_get_vector_affinity function
date: 2 weeks ago
config: xtensa-allyesconfig (attached as .config)
compiler: xtensa-linux-gcc (GCC) 7.2.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout 6082d9c9c94a408d7409b5f2e4e42ac9e8b16d0d
# save the attached .config to linux build tree
make.cross ARCH=xtensa
