Subject: usb: quirks: Add reset-resume quirk for QCA6174 Rome Bluetooth
Date: Sun, 31 Dec 2017 18:13:35 +0100 [thread overview]
Message-ID: <20171231171335.12020-1-leif.linux@gmail.com> (raw)
This is a rework of reverted commit fd865802c66bc451dc515ed89360f84376ce1a56
The issue is that some QCA Rome bluetooth controllers stop functioning upon resume from suspend.
These devices seem to be losing power during suspend. This patch will enable
reset_resume in usb core (instead of btusb) and will target the specific device 0x0cf3:0xe300
