Subject: crypto: caam - Fix opencoded cpumask_next_wrap() in caam_drv_ctx_init()
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4b7ed1ce411e5049b3c842009981c9c5191fea49;p=thirdparty%2Flinux.git

crypto: caam - Fix opencoded cpumask_next_wrap() in caam_drv_ctx_init()

The dedicated cpumask_next_wrap() is more verbose and better optimized
comparing to cpumask_next() followed by cpumask_first().
