There isn't really support for documenting function pointer struct members in kernel-doc, but at least reference the member properly.

Late Binding is a runtime firmware upload/update mechanism that allows payloads, such as fan control and voltage regulator, to be securely delivered and applied without requiring SPI flash updates or system reboots. This driver enables the Xe graphics driver and other user-space tools to push such firmware blobs to the authentication firmware via the MEI interface. The driver handles authentication, versioning, and communication with the authentication firmware, which in turn coordinates with the PUnit/PCODE to apply the payload. This is a foundational component for enabling dynamic, secure, and re-entrant configuration updates on platforms like Battlemage.
