+Subject: Bluetooth: btusb: fix QCA Rome suspend/resume
+
+From: Leif Liddy <leif.linux@gmail.com>
+
+commit fd865802c66bc451dc515ed89360f84376ce1a56 upstream.
+
+There's been numerous reported instances where BTUSB_QCA_ROME
+bluetooth controllers stop functioning upon resume from suspend. These
+devices seem to be losing power during suspend. Patch will detect a status
+change on resume and perform a reset.
