Subject: [PATCH v2 08/10] scsi: qla2xxx: Use FIELD_GET() to extract PCIe capability fields
Date: Wed, 13 Sep 2023 15:27:46 +0300	[thread overview]
Message-ID: <20230913122748.29530-9-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20230913122748.29530-1-ilpo.jarvinen@linux.intel.com>

Use FIELD_GET() to extract PCIe capability registers field instead of
custom masking and shifting.
