How about
rtctl_pos = pci_pcie_cap(dev) + PCI_EXP_RTCTL;
?
The pci_pcie_cap() returns PCIe capability offset saved in struct pci_dev.
By using this, we can avoid redundant search in PCI configuration space.
While I agree with the comment, I'd prefer to change this with a separate
patch, unless the entire patchset misses the merge window.
Ok. Actually, I didn't realize your set of patches was already in
linux-next, sorry. I'll send a patch as a separate one.
Thanks,
Kenji Kaneshige
