[PATCH 4.19 029/639] PCI: iproc: Remove PAXC slot check to allow VF support

From: Greg Kroah-Hartman
Date: Fri Jan 24 2020 - 05:09:33 EST


From: Jitendra Bhivare <jitendra.bhivare@xxxxxxxxxxxx>

[ Upstream commit 4da6b4480766e5bc9c4d7bc14bf1d0939a1a5fa7 ]

Fix previous incorrect logic that limits PAXC slot number to zero only.
In order for SRIOV/VF to work, we need to allow the slot number to be
greater than zero.

Fixes: 46560388c476c ("PCI: iproc: Allow multiple devices except on PAXC")
