version.map are now optional for drivers if no symbol is exported. Having no symbol exported from a library does not make sense. Catch all empty maps and warn about them. Example: $ ./devtools/check-symbol-maps.sh Found empty maps: drivers/crypto/uadk/version.map drivers/net/gve/version.map drivers/net/idpf/version.map Signed-off-by: David Marchand <david.marchand@redhat.com> Acked-by: Bruce Richardson <bruce.richardson@intel.com> Tested-by: Ferruh Yigit <ferruh.yigit@amd.com>
