Subject: [PATCH 4/8] powerpc/perf: Use existing out label in power_pmu_enable()
Date: Mon, 24 Jun 2013 21:28:52 +1000 [thread overview]
Message-ID: <1372073336-8189-4-git-send-email-michael@ellerman.id.au> (raw)
In-Reply-To: <1372073336-8189-1-git-send-email-michael@ellerman.id.au>
In power_pmu_enable() we can use the existing out label to reduce the
number of return paths.
