[ Upstream commit 04507c0a9385cc8280f794a36bfff567c8cc1042 ]
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.
