w1: Organize driver source to natural/common order
Structures and functions should be ordered such that forward declaration use is minimized. MODULE_* macros should immediately follow the structures and functions upon which they act. Remaining MODULE_* macros should be at the end of the file in alphabetical order. Signed-off-by: Andrew F. Davis <afd@ti.com> Acked-by: Evgeniy Polyakov <zbr@ioremap.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
