Subject: [PATCH 4.9 115/117] USB: Add NO_LPM quirk for Kingston flash drive

From: Alan Stern <stern@...land.harvard.edu>

commit afaa2e745a246c5ab95103a65b1ed00101e1bc63 upstream.

In Bugzilla #208257, Julien Humbert reports that a 32-GB Kingston
flash drive spontaneously disconnects and reconnects, over and over.
Testing revealed that disabling Link Power Management for the drive
fixed the problem.

This patch adds a quirk entry for that drive to turn off LPM permanently.
