Subject: net/mlx5: Simplify cpumask operations in comp_irq_request_sf()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=32fbe56b3f8a81383bc38d51e76edb74031d34c8;p=thirdparty%2Flinux.git

net/mlx5: Simplify cpumask operations in comp_irq_request_sf()

Combine cpumask_copy() and cpumask_andnot() into a single
cpumask_andnot() since the function can take cpu_online_mask
directly as the source.
