Subject: [PATCH] cpupower : frequency-set -r option misses the last cpu in related cpu list
Date:   Wed, 29 May 2019 04:30:33 -0500
Message-Id: <20190529093033.30068-1-huntbag@linux.vnet.ibm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

To set frequency on specific cpus using cpupower, following syntax can
be used :
cpupower -c #i frequency-set -f #f -r

While setting frequency using cpupower frequency-set command, if we use
'-r' option, it is expected to set frequency for all cpus related to
cpu #i. But it is observed to be missing the last cpu in related cpu
list. This patch fixes the problem.
