As hotplug is not the only driver touching LNKCTL, use the RMW capability accessor which handles concurrent changes correctly.

• pcie_capability_clear_and_set_word(pdev, PCI_EXP_LNKCTL,

• 			   PCI_EXP_LNKCTL_LD,
  

• 			   !enable ? PCI_EXP_LNKCTL_LD : 0);
  

enable ? 0 : PCI_EXP_LNKCTL_LD);

easier to read and get.
