(+cc Fabio Estevam)

Hi all,

The same patch was already sent by Fabio Estevam a month ago.[1]
Also, it was applied to pci/next tree.[2]

[1] http://www.spinics.net/lists/linux-pci/msg26873.html
[2] http://git.kernel.org/cgit/linux/kernel/git/helgaas/pci.git/commit/?h=next&id=ebb034a4ce9fc37877b3df2b85b9c33d43349586

Best regards,
Jingoo Han
