[PATCH V2 3/5] arch_topology: Covert switch block to if block

From: Viresh Kumar
Date: Wed Jun 21 2017 - 00:47:15 EST


We only need to take care of one case here (CPUFREQ_NOTIFY) and there is
no need to add an extra level of indentation to the case specific code
by using a switch block. Use an if block instead.

Also add some blank lines to make the code look better.
