Subject: cpufreq/amd-pstate-ut: Run on all of the correct CPUs
X-Git-Tag: v6.15-rc1~191^2~4^2~2^2~9
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2aac38ac06cb751bd3e672a4fb1eb3073f1866ab;p=thirdparty%2Fkernel%2Flinux.git

cpufreq/amd-pstate-ut: Run on all of the correct CPUs

If a CPU is missing a policy or one has been offlined then the unit test
is skipped for the rest of the CPUs on the system.

Instead; iterate online CPUs and skip any missing policies to allow
continuing to test the rest of them.
