Subject: perf test: check if cpu_map__new() return NULL
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=98d77b78504a423fca911a26a17bee00ef2fdda2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

perf test: check if cpu_map__new() return NULL

It looks like we should check if cpus is NULL after

	cpus = cpu_map__new(NULL);

in test__open_syscall_event_on_all_cpus().
