Subject: [PATCH 4/6] cpuidle: sysfs: Remove sysfs_switch and switch attributes
Date: Tue, 19 May 2020 14:25:23 +0800	[thread overview]
Message-ID: <1589869525-29893-5-git-send-email-guohanjun@huawei.com> (raw)
In-Reply-To: <1589869525-29893-1-git-send-email-guohanjun@huawei.com>

Since the cpuidle governor can be switched via sysfs in default,
remove sysfs_switch and cpuidle_switch_attrs.
