Subject: [PATCH AUTOSEL 4.14 005/371] PCI: iproc: Remove PAXC slot check to allow VF support
Date: Thu, 16 Jan 2020 12:11:13 -0500
Message-ID: <20200116171719.16965-5-sashal@kernel.org> (raw)
In-Reply-To: <20200116171719.16965-1-sashal@kernel.org>

From: Jitendra Bhivare <jitendra.bhivare@broadcom.com>

[ 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")
