From 34298422cc442d65e0ee271e47f2926f63fe91e8 Mon Sep 17 00:00:00 2001 From: Julian Wiedmann Date: Thu, 28 Mar 2019 13:48:44 +0100 Subject: s390/qdio: fix output of DSCI value in debug file The DSCI is a 1-byte field, placed at the start of an u32. So when printing it to a queue's debug state, limit the output to the part that's actually occupied by the DSCI. When the DSCI is set this gives us the expected output of '1', rather than the current (obscure) value of '16777216'.
