Subject: GCC4.6: Squash warning in cmd_mem.c
X-Git-Tag: submit/tizen/20171113.013653~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F31%2F159131%2F1;p=profile%2Fmobile%2Fplatform%2Fkernel%2Fu-boot-tm1.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.
