Hi Francois,

The PCIe changes are good, however I think using gotos here doesn't add anything as there's no difficult locking to navigate and makes the code harder to read.
both out: and err_out: are used to return an error, and the backwards jumping goto makes me a bit uncomfortable. Could you respin with just the PCIe changes?

Cheers,

Mark
