Subject: perf tools: Fix compile of util/tsc.c
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=602bab1b883090ffd125ed1253fe8ec127c048b1;p=openwrt%2Fstaging%2Fblogic.git

perf tools: Fix compile of util/tsc.c

On Fedora 18, with gcc 4.6.4 compile fails with:

arch/x86/util/tsc.c: In function ‘perf_time_to_tsc’:
arch/x86/util/tsc.c:13:6: error: declaration of ‘time’ shadows a global declaration [-Werror=shadow]
cc1: all warnings being treated as errors
make: *** [/tmp/junk/arch/x86/util/tsc.o] Error 1
make: *** Waiting for unfinished jobs....

Fix by renaming the local variable.
