[PATCH 5.4 059/367] cpufreq: powernow-k8: Use related_cpus instead of cpus in driver.exit()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


5.4-stable review patch.  If anyone has any objections, please let me know.


From: Liao Chang <liaochang1@xxxxxxxxxx>

[ Upstream commit 03997da042dac73c69e60d91942c727c76828b65 ]

Since the 'cpus' field of policy structure will become empty in the
cpufreq core API, it is better to use 'related_cpus' in the exit()
callback of driver.
