[PATCH 4.14 05/52] s390/qeth: fix early exit from error path

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Julian Wiedmann <j...@linux.vnet.ibm.com>


[ Upstream commit 83cf79a2fec3cf499eb6cb9eb608656fc2a82776 ]

When the allocation of the addr buffer fails, we need to free
our refcount on the inetdevice before returning.
