During the review of a patch for pci_endpoint_test driver [1], Greg spotted the wrong usage of the return value of IOCTLs in the driver. This series fixes that by returning 0 for success and negative error code for failure. Relevant change is also made to the userspace tool and the Documentation. Along with those, there are couple more patches fixing other small issues I noted. NOTE: I have just compile tested this series. So it'd be good if someone can test it on the PCI endpoint setup. Thanks, Mani [1] https://lore.kernel.org/all/20220816100617.90720-1-mie@xxxxxxxxxx/ Changes in v2: * Fixed the error numbers in pci_endpoint_test * Added Fixes tag and CCed stable list for relevant patches. The patches should get backported until 5.10 kernel only. Since for the LTS kernels before that, the pci_endpoint_test driver was not supporting all commands.
