Subject: [PATCH 1/2] mtip32xx: use PCI #defines instead of numbers
Date: Tue, 26 Jan 2021 14:04:32 -0600 [thread overview]
Message-ID: <20210126200433.2911982-2-helgaas@kernel.org> (raw)
In-Reply-To: <20210126200433.2911982-1-helgaas@kernel.org>
From: Bjorn Helgaas <bhelgaas@google.com>
Use PCI #defines for PCIe Device Control register values instead of
hard-coding bit positions. No functional change intended.
