+Subject: [PATCH v3 1/6] usb: xhci: plat: fix adding usb3-lpm-capable quirk
+
+The xhci->quirks member is overwritten in xhci_gen_setup() with the
+quirks given through the module load parameter. Without this patch the
+usb3-lpm-capable quirk will be over written before it gets used. This
+patch moves the quirks code to the xhci_plat_quirks() callback function
+which gets called directly after the quirks member variable is
+overwritten with the module load parameter.
+
+I do not have any hardware which is using usb3-lpm-capabls so I can not
+test this on real hardware.
