Subject: rapidio/tsi721: use pci_enable_msix_exact() instead of pci_enable_msix()
X-Git-Tag: v3.16-rc1~82^2~4^2~78
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1c92ab1e742b0636e5c4c63792e20020cdf16caf;p=platform%2Fkernel%2Flinux-exynos.git

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.
