[PATCH V3 5/9] cpufreq: arm_big_little: Make ->get_transition_latency() mandatory

From: Viresh Kumar
Date: Wed Jul 19 2017 - 06:14:44 EST


All users of arm_big_little driver are defining it and there is no need
to keep it optional.

Make it mandatory to remove the always true conditional statement.
