Subject: cpufreq: Print driver name if cpufreq_suspend() fails
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e9a7cc1d97f13f11970f7c484bdfc0502efc4223;p=openwrt%2Fstaging%2Fblogic.git

cpufreq: Print driver name if cpufreq_suspend() fails

Instead of printing the policy, which is incidentally a kernel pointer,
so with limited interest, print the cpufreq driver name that failed to
be suspend, which is more useful for debugging.
