cpufreq: Make cpufreq_quick_get() safe to call The function, cpufreq_quick_get, accesses the global 'cpufreq_driver' and its fields without taking the associated lock, cpufreq_driver_lock. Without the locking, nothing guarantees that 'cpufreq_driver' remains consistent during the call. This patch fixes the issue by taking the lock before accessing the data structure.
