Subject: ixgbe: Use pci_vfs_assigned instead of ixgbe_vfs_are_assigned
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e507d0cdb3d8b79d806645e68aa310ddb12bfe76;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ixgbe: Use pci_vfs_assigned instead of ixgbe_vfs_are_assigned

This change makes it so that the ixgbe driver uses the generic helper
pci_vfs_assigned instead of the ixgbe specific function
ixgbe_vfs_are_assigned.
