[PATCH] PCI/ASPM: add missing newline when printing parameter 'policy' by sysfs

[Xiongfeng Wang]

When I cat ASPM parameter 'policy' by sysfs, it displays as follows.
It's better to add a newline for easy reading.

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