+Subject: [PATCH] opengl: Bail if cached shader fails to load
+
+QOpenGLProgramBinaryCache::setProgramBinary() should check
+GL_LINK_STATUS after glProgramBinary(), but doesn't.
+
+In practice, this means that SDDM is a white screen, and KDE is just
+a gray task bar.
+
+So far, Qt tries to check this using its internal ::link() function.
+But in case the cached binary fails to load, Qt currently attempts to
+link the inexistent program, resulting in a zero-length, fixed
+pipeline shader.
+
+Checking this already in ::setProgramBinary() makes the call to
+::link() superfluous, so we remove that as well.
