Existing code updates cupfreq policy only while executing cpufreq_apply_cooling() function (i.e. when notify_device != NOTIFY_INVALID). It doesn't apply constraints when cpufreq policy update happens from any other place but it should update the cpufreq policy with thermal constraints every time when there is a cpufreq policy update, to keep state of cpufreq_cooling_device and max_feq of cpufreq policy in sync. For instance while resuming cpufreq updates cpufreq_policy and it restores default policy->usr_policy values irrespective of cooling device's cpufreq_state since notification gets missed because (notify_device == NOTIFY_INVALID). Another problem, is that userspace is able to change max_freq irrespective of cooling device's state, as notification gets missed. This patch modifies code to maintain a global cpufreq_dev_list and applies constraints of all matching cooling devices for policy's cpu when there is any policy update(ends up applying the lowest max_freq among the matching cpu cooling devices). This patch also removes redundant check (max_freq > policy->user_policy.max), as cpufreq framework takes care of user_policy constraints already where ever required, otherwise its causing an issue while increasing max_freq in normal scenerio as it restores max_freq with policy->user_policy.max which is old (smaller) value.
