| Subject: usb: mtu3: fix error return code in ssusb_gadget_init() |
| |
| From: Chunfeng Yun <chunfeng.yun@mediatek.com> |
| |
| |
| [ 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. |
