commit d44238d8254a36249d576c96473269dbe500f5e4 upstream.
I have a ASUS PN51 S mini pc that has two xhci devices. One from AMD, and other from ASMEDIA. The one from ASMEDIA have problems when resume from suspend, and keep broken until unplug the power cord. I use this kernel parameter: xhci-hcd.quirks=128 and then it works ok. I make a path to reset only the ASMEDIA xhci.
