From 0b698c838e84149b690c7e979f78cccb6f8aa4b9 Mon Sep 17 00:00:00 2001 From: Julian Wiedmann Date: Mon, 23 Dec 2019 15:03:26 +0100 Subject: [PATCH] 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).
