Subject: ARM: perf: remove redundant NULL check on cpu_pmu
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=1764c591dfed2ce7075465df0591ce9564ff37a1;p=deliverable%2Flinux.git

ARM: perf: remove redundant NULL check on cpu_pmu

cpu_pmu has already been dereferenced before we consider invoking the
->reset function, so remove the redundant NULL check.
