When AF and PF drivers\nare built as modules, the PF driver may probe before AF reinitializes\nthe hardware.\n\nThe PF driver treats the RVUM block revision as an indication that AF\ninitialization is complete. If this value is left uncleared at shutdown,\nPF may incorrectly assume AF is ready and access stale hardware state,\nleading to a crash.\n\nClear the RVUM block revision during AF shutdown to avoid PF\nmis-detecting AF readiness after kexec."
