From: Sam Ravnborg Date: Sun, 9 Dec 2007 07:55:13 +0000 (+0100) Subject: kbuild: fix building with O=.. options X-Git-Tag: firefly_0821_release~24071^2 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=18c32dac75b187d1a4e858f3cfdf03e844129f5e;p=firefly-linux-kernel-4.4.55.git kbuild: fix building with O=.. options The check introduced in commit: 4f1127e204377cbd2a56d112d323466f668e8334 "kbuild: fix infinite make recursion" caused certain external modules not to build and also caused 'make targz-pkg' to fail. This is a minimal fix so we revert to previous behaviour - but we do not overwrite the Makefile in the top-level directory.
