Subject[PATCH AUTOSEL for 4.9 46/55] drm/omap: Fix error handling path in 'omap_dmm_probe()'
Date
From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit 8677b1ac2db021ab30bb1fa34f1e56ebe0051ec3 ]

If we don't find a matching device node, we must free the memory allocated
in 'omap_dmm' a few lines above.

Fixes: 7cb0d6c17b96 ("drm/omap: fix TILER on OMAP5")
