It applies cleanly to 6.12.112 and is already in 6.18.y and 7.2.y. 97110d42680e692020154f9aa89298c038196055 PCI: endpoint: test: Synchronously cancel command handler work pci_epf_test_epc_deinit() and pci_epf_test_link_down() use the asynchronous cancel_delayed_work(), so the command handler can still run while DMA channels and BARs are released. The fix waits for it. Build-tested on 6.12.y (CONFIG_PCI_EPF_TEST=m, CONFIG_WERROR=y); no runtime testing. Prepared with LLM assistance. Thanks, Artem Dinaburg
