    Subject[PATCH v4 14/23] cxl/port: Remove Component Register base address from struct cxl_port
    Date
    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.
