From 73bf0fc2b03d1f4fdada0ec430dc20bfb089cfd5 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Tue, 5 Feb 2013 22:21:14 +0100 Subject: [PATCH] cpufreq: Don't remove sysfs link for policy->cpu "cpufreq" directory in policy->cpu is never created using sysfs_create_link(), but using kobject_init_and_add(). And so we shouldn't call sysfs_remove_link() for policy->cpu(). sysfs stuff for policy->cpu is automatically removed when we call kobject_put() for dying policy.
