    Subject[PATCH 5.11 385/775] tools/testing/scatterlist: Fix overflow of max segment size
    Date
    From: Maor Gottlieb <maorg@nvidia.com>

    [ Upstream commit 96667052149da3855c4361925324b690c687152f ]

    Because SCATTERLIST_MAX_SEGMENT was removed and replaced with UINT_MAX,
    the test overflows the max_sgement variable. Remove this case.

    Fixes: 7a60c2dd0f57 ("drm: Remove SCATTERLIST_MAX_SEGMENT")
