    Subject[PATCH 5.2 383/413] gpu: ipu-v3: ipu-ic: Fix saturation bit offset in TPMEM
    Date
    From: Steve Longerbeam <slongerbeam@gmail.com>

    commit 3d1f62c686acdedf5ed9642b763f3808d6a47d1e upstream.

    The saturation bit was being set at bit 9 in the second 32-bit word
    of the TPMEM CSC. This isn't correct, the saturation bit is bit 42,
    which is bit 10 of the second word.

    Fixes: 1aa8ea0d2bd5d ("gpu: ipu-v3: Add Image Converter unit")
