commit 5ebdc6be16c2000e37fcb8b4072d442d268ad492 upstream.
_of_phy_get() will directly return when suffers of_device_is_compatible()
error, but it forgets to decrease refcount of OF node @args.np before error
return, the refcount was increased by previous of_parse_phandle_with_args()
so causes the OF node's refcount leakage.
Fix by decreasing the refcount via of_node_put() before the error return.
