Subject: perf_counter: Fix throttle/unthrottle event logging
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=966ee4d6b887c14159043ac80b8c3661d2bbe5e2;p=openwrt%2Fstaging%2Fblogic.git

perf_counter: Fix throttle/unthrottle event logging

Right now we only print PERF_EVENT_THROTTLE + 1 (ie PERF_EVENT_UNTHROTTLE).
Fix this to print both a throttle and unthrottle event.
