From 87ebb94e28ccac00bacba0d6a0dac0aac5b9c63b Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 10 Jul 2017 03:32:33 +0900 Subject: kbuild: remove useless $(gen) variable in Makefile.headersinst We have no true case for the $(if $(gen), ...) conditional. Drop it to simplify the gendir calculation.
