-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.
