[PATCH v2 04/10] igb_uio: dont wrap pci_num_vf function needlessly

[Stephen Hemminger <stephen-OTpzqLSitTUnbdJkjeBofR2eb7JE58TQ@public.gmane.org>]

[-- Attachment #1: igb_uio-better-pci-num-vf.patch --]
[-- Type: text/plain, Size: 1242 bytes --]

It is better style to just use the pci_num_vf directly, rather
than wrapping it with a local (but globally named) function with
the same effect.
