Subject: mtip32xx: Use pci_enable_msi() instead of pci_enable_msi_range()
X-Git-Tag: v4.14-rc1~7806^2~9
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c94efe36e283f2837dd4a21eab4b3f8492e3f325;p=platform%2Fkernel%2Flinux-rpi.git

mtip32xx: Use pci_enable_msi() instead of pci_enable_msi_range()

Commit "mtip32xx: Use pci_enable_msix_range() instead of
pci_enable_msix()" was unnecessary, since pci_enable_msi()
function is not deprecated and is still preferable for
enabling the single MSI mode. This update reverts usage of
pci_enable_msi() function.

Besides, the changelog for that commit was bogus, since
mtip32xx driver uses MSI interrupt, not MSI-X.
