Subject: [PATCH v3 2/3] PCI/MSI: Move MSI/MSI-X flags updaters to msi.c
Date: Thu,  3 Dec 2020 12:51:09 -0600	[thread overview]
Message-ID: <20201203185110.1583077-3-helgaas@kernel.org> (raw)
In-Reply-To: <20201203185110.1583077-1-helgaas@kernel.org>

From: Bjorn Helgaas <bhelgaas@google.com>

pci_msi_set_enable() and pci_msix_clear_and_set_ctrl() are only used from
msi.c, so move them from drivers/pci/pci.h to msi.c.  No functional change
intended.
