Subject: [PATCH v2 9/9] PCI: hotplug: Prefix ctrl_*() dmesg logs with pciehp slot name
Date:   Thu,  2 May 2019 22:59:46 -0500
Message-Id: <20190503035946.23608-10-fred@fredlawl.com>
In-Reply-To: <20190503035946.23608-1-fred@fredlawl.com>
References: <20190503035946.23608-1-fred@fredlawl.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Remove current uses of "Slot(%s)" and then prefix ctrl_*() dmesg
with pciehp slot name to include the slot name for all uses of ctrl_*()
wrappers.
