+Subject: [PATCH xserver] glamor: glamor_egl_get_display: Return NULL if
+ eglGetPlatformDisplayEXT returns NULL
+
+If the libEGL we are using has eglGetPlatformDisplayEXT, yet it still
+returns NULL, then this very likely means that it does not support
+the type (e.g. EGL_PLATFORM_GBM_MESA) passed in, and then returning NULL
+is the right thing to do.
+
+This avoids falling back to an eglGetDisplay() implementation which does
+not understands the passed in gbm handle, treats it as a pointer to
+something else completely, followed by a crash sooner or later.
+
+Specifically this fixes using the nvidia binary driver, with nvidia's
+libEGL + the modesetting driver on a secondary GPU crashing inside
+glamor_egl_init() sometimes.
