Message

This series reworks interrupt enabling in 'xhci-pci.c'.
Instead of MSI-X, MSI and legacy IRQ enabling being split
over three functions, rework them into one simple function.

Niklas Neronin (7):
  xhci: check if legacy irq is available before using it as fallback
  xhci: add handler for only one interrupt line
  xhci: refactor static MSI-X function
  xhci: refactor static MSI function
  xhci: change 'msix_count' to encompass MSI or MSI-X vectors
  xhci: rework 'xhci_try_enable_msi()' MSI and MSI-X setup code
  xhci: minor coding style cleanup in 'xhci_try_enable_msi()'
