Subject: rapidio/tsi721: use pci_enable_msix_exact() instead of pci_enable_msix()
X-Git-Tag: next-20140530~2^2~46

rapidio/tsi721: use pci_enable_msix_exact() instead of pci_enable_msix()

As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers using these two
interfaces need to be updated to use the new pci_enable_msi_range() or
pci_enable_msi_exact() and pci_enable_msix_range() or
pci_enable_msix_exact() interfaces.

The patch has no runtime effect.
