Like we did for the linux kernel, change linux-headers to only check the license hashes for the latest known version as the content of COPYING has changed between versions. To simplify the test, we introduce an intermediate, blind option that get selected when the latest kernel sources are used. Reported-by: Peter Korsgaard <peter@korsgaard.com> Signed-off-by: Yann E.
