Subject: [PATCH] kernel/cpu: Convert snprintf() to sysfs_emit()
Per filesystems/sysfs.rst, show() should only use sysfs_emit()
or sysfs_emit_at() when formatting the value to be returned to user space.
coccinelle complains that there are still a couple of functions that use
snprintf(). Convert them to sysfs_emit().
No functional change intended.
