Subject: [PATCH AUTOSEL 6.6 21/36] PCI: mvebu: Use FIELD_PREP() with Link Width
Date: Tue, 7 Nov 2023 10:46:03 -0500 [thread overview]
Message-ID: <20231107154654.3765336-21-sashal@kernel.org> (raw)
In-Reply-To: <20231107154654.3765336-1-sashal@kernel.org>
From: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>
[ Upstream commit 408599ec561ad5862cda4f107626009f6fa97a74 ]
mvebu_pcie_setup_hw() setups the Maximum Link Width field in the Link
Capabilities registers using an open-coded variant of FIELD_PREP() with
a literal in shift. Improve readability by using
FIELD_PREP(PCI_EXP_LNKCAP_MLW, ...).
