Subject: [PATCH 1/3] treewide: remove explicit rules for *offsets.s
Date: Sat, 22 Dec 2018 18:50:33 +0900 [thread overview]
Message-ID: <1545472235-12782-1-git-send-email-yamada.masahiro@socionext.com> (raw)
These explicit rules are unneeded because scripts/Makefile.build
provides a pattern rule to create %.s from %.c
Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
