Subject: [PATCH]dri2: Check for dummyContext to see if the glx_context is valid
Patch-mainline: to be upstreamed
References: boo#962609
Signed-off-by: Egbert Eich <eich@suse.com>
According to the comments in src/glx/glxcurrent.c __glXGetCurrentContext()
always returns a valid pointer. If no context is made current, it will
contain dummyContext. Thus a test for NULL will always fail.
