Subject: cpufreq: Remove the ->stop_cpu() driver callback
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3e0f897fd92662f0ff21ca1759d724a9ad574858;p=linux.git

cpufreq: Remove the ->stop_cpu() driver callback

Now that all users of ->stop_cpu() have been migrated to using other
callbacks, drop it from the core.
