This variable was removed upstream in commitbad6beb2c0("kbuild: remove extmod_prefix, MODORDER, MODULES_NSDEPS variables"). However, it was mistakenly kept during a merge conflict resolution. Drop it! Fixes:f9d4616300("Merge 'Merge tag 'kbuild-v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild'") Change-Id: I8e5b6c10ab82b8ccc16a1bb575b96c3f68f1f9e5 Signed-off-by: Carlos Llamas <cmllamas@google.com>
