From a34e63b14486e98cf78c99bf8ef141de7508dbc2 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 27 Jul 2015 23:11:50 +0200 Subject: [PATCH] cpufreq: Pass CPU number to cpufreq_policy_alloc() Change cpufreq_policy_alloc() to take a CPU number instead of a CPU device pointer as its argument, as it is the only function called by cpufreq_add_dev() taking a device pointer argument at this point. That will allow us to split the CPU online part from cpufreq_add_dev() more cleanly going forward. Signed-off-by: Rafael J.
