I think I'm OK with this, and since they all depend on the first PCI
patch, it will probably be easiest to merge them all through the PCI
tree. I'm happy to do that, but can you please:
- Update the subject lines so they start with a capital letter to
match the historical convention.
- Use "MSI-X" instead of "MSIx" so it matches the spec and other
usage in the kernel.
- Add "()" after function names, e.g.,
"pci_alloc_irq_vectors_affinity()" instead of
"pci_alloc_irq_vectors_affinity".
- Reorder them so the actual fix (02/15) is first and the cleanups
later.
- Post them all to linux-pci (I only saw the drivers/pci patches).
- If possible, post them with all the patches as replies to the
cover letter. These all appear to be unrelated messages, which
makes it a bit of a hassle to collect them all up.
