[ Upstream commit 3167e3d340c092fd47924bc4d23117a3074ef9a9 ]

When I cat ASPM parameter 'policy' by sysfs, it displays as follows. Add a
newline for easy reading. Other sysfs attributes already include a
newline.

[root@localhost ~]# cat /sys/module/pcie_aspm/parameters/policy
[default] performance powersave powersupersave [root@localhost ~]#
