Subject: usb: mtu3: fix error return code in ssusb_gadget_init()
From: Chunfeng Yun <chunfeng.yun@xxxxxxxxxxxx>
[ Upstream commit c162ff0aaaac456ef29aebd1e9d4d3e305cd3279 ]
When failing to get IRQ number, platform_get_irq() may return
-EPROBE_DEFER, but we ignore it and always return -ENODEV,
so fix it.
