Subject: GCC4.6: Squash warning in cmd_mem.c
X-Git-Tag: v2011.12-rc1~610
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=f3b3c3df189f4d35c903c3472619017d0bd1baa7;p=oweals%2Fu-boot.git

GCC4.6: Squash warning in cmd_mem.c

cmd_mem.c: In function ‘do_mem_loop’:
cmd_mem.c:474:25: warning: variable ‘junk’ set but not used
[-Wunused-but-set-variable]

The assigned variable can be removed because the pointers are volatile so
accesses to their addresses are always generated.
