4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dinghao Liu <dinghao.liu@xxxxxxxxxx>
[ Upstream commit 759c409bc5fc496cbc22cd0b392d3cbb0c0e23eb ]
The dln2_free() already contains usb_put_dev(). Therefore,
the redundant usb_put_dev() before dln2_free() may lead to
a double free.
Fixes: 96da8f148396 ("mfd: dln2: Fix memory leak in dln2_probe()")
