SubjectRe: [PATCH 5/7] driver core: Use sysfs_rename_link in device_rename
Quoting Eric W. Biederman (ebiederm@xmission.com):
> From: Eric W. Biederman <ebiederm@xmission.com>
>
> Don't open code the renaming of symlinks in sysfs
> instead use the new helper function sysfs_rename_link
>
> Signed-off-by: Eric W. Biederman <ebiederm@aristanetworks.com>

Acked-by: Serge Hallyn <serue@us.ibm.com>
