Subject: USB: Add NO_LPM quirk for Kingston flash drive
From: Alan Stern <stern@xxxxxxxxxxxxxxxxxxx>
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.
