[Test] Apply this patch to the kernel tree and build it with: sudo make -C linux/tools/testing/selftests TARGETS=powerpc With this error fixed, test compliation can finish without any issue. [Where problems could occur] Change for test case, no impact to acutal function. [Original Bug Report] Issue found with K-5.19.0-28-generic on P9 node baltar This should not be considered as a regression since ubuntu_kernel_selftests will be blocked by the net test crash before this powerpc tests can be started. This was found by manually running the test.
