this "problem" exists since the driver was introduced in commit
ceb80363b2ec ("USB: net2272: driver for PLX NET2272 USB device
controller"). Might be worth a Fixes: line.
I wonder if the better fix would be:
diff --git a/drivers/usb/gadget/udc/net2272.c b/drivers/usb/gadget/udc/net2272.c
index 12e76bb62c20..19bbc38f3d35 100644
--- a/drivers/usb/gadget/udc/net2272.c
+++ b/drivers/usb/gadget/udc/net2272.c
@@ -2650,7 +2650,7 @@ net2272_plat_probe(struct platform_device *pdev)
goto err_req;
}
- ret = net2272_probe_fin(dev, IRQF_TRIGGER_LOW);
+ ret = net2272_probe_fin(dev, irqflags);
if (ret)
