== SRU Justification ==
Some QCA ROME bluetooth devices does not work after runtime suspend/resume
after SRU LP: #1734020.
The commit let btusb reset at second time it resume, i.e. btusb_open(). The
btusb stops working because the reset happens *after* btusb_open(). The reset
should be done at hub port initialization, before btusb_probe().
Revert the bad commit and use the reset-resume quirk in USB core
Cherry-picked the commit into Artful/OEM kernel and the issue is fixed.
Low. This is limited to QCA Rome, also verified by the original quirk author.
