Subject: cpufreq: minor clean-ups for ondemand governor on Xen.
X-Git-Tag: xen-3.2.0~21^2^2~28^2^2~22^2^2~9^2~9
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=4054d46ffa53610a88ca66b1067822214e1fcd2b;p=xenclient%2Fkernel.git

cpufreq: minor clean-ups for ondemand governor on Xen.

The cpufreq ondemand governor patch for Xen included some out
of order code and some test code; re-order the code to assign
a variable before passing it to a function and remove the
test code.
