[PATCH] cpufreq: acpi-cpufreq: make Intel/AMD MSR access, io port access static
From: Jisheng Zhang
Date: Tue Mar 22 2016 - 10:38:34 EST
These frequency register read/write operations' implementations for the
given processor (Intel/AMD MSR access or I/O port access) are only used
internally in acpi-cpufreq, so make them static.
