Subject: perf symbols: Check the right return variable
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=37fe5fcb7a5b5235c8b71bf5469ce4c7246e3fab;p=openwrt%2Fstaging%2Fblogic.git

perf symbols: Check the right return variable

In function dso__split_kallsyms(), curr_map saves the return value
of map__new2. So check it instead of var map after the call returns.
