Subject: ifenslave: Fix unused variable warnings.
X-Git-Tag: v3.3-rc1~182^2~476
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=450faacc621dbe0a4945ed8292afd45f4602d263;p=platform%2Fkernel%2Flinux-3.10.git

ifenslave: Fix unused variable warnings.

Documentation/networking/ifenslave.c: In function ‘if_getconfig’:
Documentation/networking/ifenslave.c:508:14: warning: variable ‘mtu’ set but not used [-Wunused-but-set-variable]
Documentation/networking/ifenslave.c:508:6: warning: variable ‘metric’ set but not used [-Wunused-but-set-variable]

The purpose of this function is to simply print out the values
it probes, so...
