Subject: sched/core: fix build warning without CONFIG_CPUMASK_OFFSTACK
X-Git-Tag: accepted/tizen/unified/20230531.034423~29
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=65db1dbb024c25be0bfaddafef5e699e21d1c331;p=platform%2Fkernel%2Flinux-amlogic.git

sched/core: fix build warning without CONFIG_CPUMASK_OFFSTACK

Without CONFIG_CPUMASK_OFFSTACK, checking the address of the
cpumask_var_t gives warning. To resolve the warning, use
cpumask_available() instead of checking the pointer directly.
