Subject: [PATCH 14/20] thermal: cpu_cooling: Use cpufreq_for_each_valid_entry macro for iteration
Date: Tue, 15 Apr 2014 00:10:26 +0300 [thread overview]
Message-ID: <534C4EC2.5080008@semaphore.gr> (raw)
The cpufreq core supports the cpufreq_for_each_valid_entry macro
helper for iteration over the cpufreq_frequency_table, so use it.
It should have no functional changes.
