Revision f84dde10d893cd368e73dda04b694169542ed792 authored by Douglas Anderson on 15 March 2019, 16:25:03 UTC, committed by Masahiro Yamada on 17 March 2019, 03:56:31 UTC
This reverts commit caf6fe91ddf62a96401e21e9b7a07227440f4185. The commit was fine but is no longer needed as of commit 3a2429e1faf4 ("kbuild: change if_changed_rule for multi-line recipe"). Let's go back to using ";" to be consistent.
