[uClinux-dev] [PATCH] m68k: fix unused variable warning in mempcy.c

[gerg]

From: Greg Ungerer <gerg at uclinux.org>

When compiling for original 68000 or ColdFire targets you will get the
following warning when compiling arch/m68k/lib/memcpy.c:

CC arch/m68k/lib/memcpy.o
arch/m68k/lib/memcpy.c: In function ?__builtin_memcpy?:
arch/m68k/lib/memcpy.c:13:15: warning: unused variable ?temp1?

This is easily fixed by moving the definition of temp1 into the code block
where it is used.
