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
