Peter Anvin Date: Wed, 6 Nov 2013 18:00:05 +0000 (-0800) Subject: x86, hyperv: Move a variable to avoid an unused variable warning X-Git-Tag: upstream/snapshot3+hdmi~4028^2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4c08edd305019061bf1ac95ce089497bdbb8b8ac;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git x86, hyperv: Move a variable to avoid an unused variable warning The variable hv_lapic_frequency causes an unused variable warning if CONFIG_X86_LOCAL_APIC is disabled. Since the variable is only used inside a small if statement, move the declaration of that variable into the if statement itself. Cc: K. Y.
