Subject: [PATCH v4 5/9] PCI/PTM: Move pci_ptm_info() body into its only caller
Date:   Fri,  9 Sep 2022 15:25:01 -0500
Message-Id: <20220909202505.314195-6-helgaas@kernel.org>
In-Reply-To: <20220909202505.314195-1-helgaas@kernel.org>

From: Bjorn Helgaas <bhelgaas@google.com>

pci_ptm_info() is simple and is only called by pci_enable_ptm().  Move the
entire body there.  No functional change intended.
