From ba5a6ecf81fc2e25a4c7b8c592143faadfdd63db Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Fri, 16 Oct 2015 15:11:24 -0700 Subject: [PATCH] xf86drm: Handle unrecognized subsystems safely in drmGetDevice[s]() Both drmGetDevice() and drmGetDevices() currently print a warning when they encounter an unknown (non-PCI) subsystem type for a device node, but they still proceed to assume that the drmDevicePtr was initialized and try to add it to the local device array. Add a 'continue' to the error case handling to bypass the rest of the processing for devices we can't handle.
