Date: Mon, 23 Dec 2019 15:03:26 +0100 From: Julian Wiedmann <jwi@...ux.ibm.com> To: David Miller <davem@...emloft.net> Cc: <netdev@...r.kernel.org>, <linux-s390@...r.kernel.org>, Heiko Carstens <heiko.carstens@...ibm.com>, Stefan Raspl <raspl@...ux.ibm.com>, Ursula Braun <ubraun@...ux.ibm.com>, Julian Wiedmann <jwi@...ux.ibm.com> Subject: [PATCH net 6/6] s390/qeth: fix initialization on old HW I stumbled over an old OSA model that claims to support DIAG_ASSIST, but then rejects the cmd to query its DIAG capabilities. In the old code this was ok, as the returned raw error code was > 0. Now that we translate the raw codes to errnos, the "rc < 0" causes us to fail the initialization of the device. The fix is trivial: don't bail out when the DIAG query fails. Such an error is not critical, we can still use the device (with a slightly reduced set of features).
