Subject: [PATCH] PCI/ASPM: Add missing newline in sysfs 'policy'

commit 3167e3d340c092fd47924bc4d23117a3074ef9a9 upstream.

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
