GNU Make is fine with # missing rule for phony targets. I also removed the comment which is # wrong irrespective of this commit. # # I minimize the change so it can be easily backported to 4.20.x # # To fix v4.20, please backport e07db28eea38 ("kbuild: fix single target # build for external module"), and then this commit. # # Link: https://bugzilla.kernel.org/show_bug.cgi?id=201891 # Fixes: e07db28eea38 ("kbuild: fix single target build for external module") # Fixes: c3ff2a5193fa ("powerpc/32: add stack protector support") #
