Where does msi_pages ever get dereferenced?
The logic here might actually still have a chance of working out OK with

Hi Kangjie,
Thanks for the patch!
Please update the subject line like this:
PCI: xilinx: Check for __get_free_pages() failure
You can always get a good idea of the style for subject lines by doing
something like this:
git log --oneline --follow drivers/pci/controller/pcie-xilinx.c
