Subject: [PATCH 3.18 061/185] drm/exynos: fix comparison to bitshift when dealing with a mask

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

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

From: Wolfram Sang <wsa+renesas@...g-engineering.com>

[ Upstream commit 1293b6191010672c0c9dacae8f71c6f3e4d70cbe ]

Due to a typo, the mask was destroyed by a comparison instead of a bit
shift.
