Subject: [PATCH 1/2] x86/pci: Simplify is_mmconf_reserved() messages
Date: Tue, 10 Jan 2023 12:02:42 -0600 [thread overview]
Message-ID: <20230110180243.1590045-2-helgaas@kernel.org> (raw)
In-Reply-To: <20230110180243.1590045-1-helgaas@kernel.org>
From: Bjorn Helgaas <bhelgaas@google.com>
is_mmconf_reserved() takes a "with_e820" parameter that only determines the
message logged if it finds the MMCONFIG region is reserved. Pass the
message directly, which will simplify a future patch that adds a new way of
looking for that reservation. No functional change intended.
