Subject: [PATCH v5 16/26] cxl/port: Remove Component Register base address from struct cxl_port
Date: Wed, 7 Jun 2023 17:16:41 -0500	[thread overview]
Message-ID: <20230607221651.2454764-17-terry.bowman@amd.com> (raw)
In-Reply-To: <20230607221651.2454764-1-terry.bowman@amd.com>

From: Robert Richter <rrichter@amd.com>

The Component Register base address @component_reg_phys is no longer
used after the rework of the Component Register setup which now uses
struct member @comp_map instead. Remove the base address.
