    Subject[PATCH 5.4 073/122] crypto: ccp - Annotate SEV Firmware file names
    Date
    From: Joerg Roedel <jroedel@suse.de>

    commit c8671c7dc7d51125ab9f651697866bf4a9132277 upstream.

    Annotate the firmware files CCP might need using MODULE_FIRMWARE().
    This will get them included into an initrd when CCP is also included
    there. Otherwise the CCP module will not find its firmware when loaded
    before the root-fs is mounted.
    This can cause problems when the pre-loaded SEV firmware is too old to
    support current SEV and SEV-ES virtualization features.

    Fixes: e93720606efd ("crypto: ccp - Allow SEV firmware to be chosen based on Family and Model")
