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.
