[PATCH v1] cpufreq: intel_pstate: Rearrange variable declaration involving __free()

Posted by Rafael J. Wysocki 4 weeks, 1 day ago

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Follow cleanup.h recommendations and define and assign a variable
in one statement when __free() is used.

No intentional functional impact.

Zhang, I said the code structure here was intentional, but that was before
the cleanup.h recommendation was pointed out to me.
