[CPUFREQ] Reevaluate users requests after denial.
Sometimes, a user or userspace daemon wants a specific frequency is set, but that frequency is (temporarily) unavailable or becomes unavailable due to e.g. thermal considerations. As soon as this situation changes, the user wish should be re-evaluated. The attached patch saves the user wish in "cpu_set_freq", and re-uses that whenever appropriate. Thanks to Thomas Renninger for testing. Signed-off-by: Dominik Brodowski <linux@brodo.de> Signed-off-by: Dave Jones <davej@redhat.com>
