Hello，
This kernel warning (irq 26 nobody cared) appears to be unrelated to my
perf userspace patch. It comes from the tps6598x Type-C controller
driver, which is likely a hardware or driver issue on the test machine.
All perf test cases passed successfully.
Please consider this as pre-existing test environment noise.
