Subject: [PATCH 4.14 113/228] MIPS: OCTEON: add missing put_device() call in dwc3_octeon_device_init()
From: Yu Kuai <yukuai3@...wei.com>
[ Upstream commit e8b9fc10f2615b9a525fce56981e40b489528355 ]
if of_find_device_by_node() succeed, dwc3_octeon_device_init() doesn't have
a corresponding put_device(). Thus add put_device() to fix the exception
handling for this function implementation.
Fixes: 93e502b3c2d4 ("MIPS: OCTEON: Platform support for OCTEON III USB controller")
