[PATCH] kernel/bounds: Provide prototype for foo

[Kieran Bingham]

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 âfooâ [-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.
