    Subject[PATCH 081/104] exynos4-is: Fix fimc-lite bayer formats
    Date
    3.5.7.22 -stable review patch.  If anyone has any objections, please let me know.

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

    From: Arun Kumar K <arun.kk@samsung.com>

    commit 3396b096c54a84603c51bd705effa88f7f5b0d76 upstream.

    The 10-bit and 12-bit Bayer output formats supported by FIMC-LITE
    actually use 16 bits where the extra bits are padded with zeros.
    The patch corrects buffer allocation for these two formats by
    modifying the depth field. This prevents memory corruption by the
    output DMA due to insufficient buffer size.
