Subject: [PATCH v7 10/27] cxl/port: Remove Component Register base address from struct cxl_dport
Date: Thu, 22 Jun 2023 15:55:06 -0500 [thread overview]
Message-ID: <20230622205523.85375-11-terry.bowman@amd.com> (raw)
In-Reply-To: <20230622205523.85375-1-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.
