Subject: [PATCH 4.14 48/62] Bluetooth: btusb: Add Dell XPS 13 9360 to btusb_needs_reset_resume_table

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hans de Goede <hdegoede@...hat.com>

commit 596b07a9a22656493726edf1739569102bd3e136 upstream.

The Dell XPS 13 9360 uses a QCA Rome chip which needs to be reset
(and have its firmware reloaded) for bluetooth to work after
suspend/resume.
