This is a note to let you know that I've just added the patch titled
USB: Add NO_LPM quirk for Kingston flash drive
to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
If you have any questions about this process, please let me know.

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.
