Subject[PATCH 4.14 44/75] usb: mtu3: fix error return code in ssusb_gadget_init()
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

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.
