Hey Ferruh,
I can confirm that this patch resolves the build issues on Fedora 20, kernel 3.19.8-100.fc20.x86_64 - thanks!
Incidentally, there is a minor warning reported when applying the patch:
Applying: igb_uio: fix unknown symbols
/home/<redacted>/.git/rebase-apply/patch:47: new blank line at EOF.

Thanks again,
Mark
