Subject[PATCH 45/54] scsi: replace cpumask_weight with cpumask_weight_gt
Date
lpfc_cpuhp_get_eq() calls cpumask_weight() to compare the weight of
cpumask with a given number. We can do it more efficiently with
cpumask_weight_gt because conditional cpumask_weight may stop
traversing the cpumask earlier, as soon as condition is met.
