From bb37a2c0b51f74e7bd9a1f87ca4ec1648e1f9398 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Tue, 27 Feb 2018 07:44:44 +0100 Subject: tests/libqos: Check for valid dev pointer when looking for PCI devices dev could be NULL if the PCI device can not be found due to some reasons, so we must not dereference the pointer in this case.
