After looking at AMD's CFI specification [1], both of the extended query tables are optional. Thus, it looks like relying that at least one of those tables exist is a bug in cfi_cmdset_0002. This patch inverts the logic and checks for unlock function pointers before exiting on error. This approach leaves place to add a call to a fixup function to try to handle chips compatible with the early AMD specification from 1995 [2].
