From 4a3dfb3fc0fb0fc9acd36c94b7145f9c9dd4d93a Mon Sep 17 00:00:00 2001 From: Richard Cochran Date: Wed, 6 Apr 2016 17:00:50 -0400 Subject: intel_idle: Remove redundant initialization calls. The function, intel_idle_cpuidle_driver_init, makes calls on each CPU to auto_demotion_disable() and c1e_promotion_disable(). These calls are redundant, as intel_idle_cpu_init() does the same calls just a bit later on. They are also premature, as the driver registration may yet fail. This patch removes the redundant code.
