From d179e22762fd38414c4108acedd5feca4cf7e0d8 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 24 Jul 2015 14:18:46 +0900 Subject: [PATCH] kbuild: fixdep: drop meaningless hash table initialization The clear_config() is called just once at the beginning of this program, but the global variable hashtab[] is already zero-filled at the start-up.
