Subject: sunxi: Avoid unused variable warning.
X-Git-Tag: v2014.10-rc1~38^2~13^2~9
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=799aff38dfc1b2d860ec8430572f9402d3ce9881;p=platform%2Fkernel%2Fu-boot.git

sunxi: Avoid unused variable warning.

Mark rc as __maybe_unused since it is infact unused on systems with neither
EMAC nor GMAC.
