Subject: [ 65/73] drm/tilcdc: Fix an incorrect condition

3.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sachin Kamat <sachin.kamat@...aro.org>

commit 9e48854c58ca9a0f39e716dcb18247bfc21e2022 upstream.

Instead of checking if num_encoders is zero, it is being assigned 0.
Convert the assignment to a check.
