[git commit] glmark2: Fix segmentation fault

Thomas Petazzoni-2
commit: https://git.buildroot.net/buildroot/commit/?id=6846d83b14fec69097a4ad6bd382c929fb91a315
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Running glmark2 on imx6 with kernel 4.11.4 and Mesa 17.1.2 leads to
a segmentation fault.

Apply Lucas Stach's patch to fix the problem while upstream glmark2
doesn't get fixed.

+Subject: [PATCH] NativeStateDRM: use fixed event context version
+
+Using the latest version is not a good idea, as the context content may
+change between versions.
+
+Fixes a segfault with new kernel and libdrm.
