Also increases the MSI interrupts. 1 patch, 1 logical change, you are making 1 patch 2 logical changes, split the patch in two and repost them please. I will consider patch v1 obsolete too, no idea why it was posted.

Lorenzo, Will do, thanks! Yes please ignore the patch v1. Thanks.

The fix enables mobiveil pcie controller to detect more than one functions per device. Also increases the MSI interrupts.
