Subject: [PATCH] kernel/bounds: Provide prototype for foo
Date: Fri, 21 Sep 2018 15:22:33 +0100	[thread overview]
Message-ID: <20180921142234.16882-1-kieran.bingham+renesas@ideasonboard.com> (raw)

kernel/bounds.c is recompiled on every build, and shows the following
warning when compiling with W=1:

  CC      kernel/bounds.s
linux/kernel/bounds.c:16:6: warning: no previous prototype for ‘foo’ [-Wmissing-prototypes]
 void foo(void)
      ^~~

Provide a prototype to satisfy the compiler.

I compile all of my incremental builds with W=1, which allows me to know
instantly if I add a new compiler warning in code I generate.

This warning always comes up and seems trivial to clean up.
