Comment 6 for bug 1991761

raof: if you mean removing the ioctl thing, they're apparently unused:

    tegra: Remove unused IOCTL implementations

    The DRM_TEGRA_GEM_{GET,SET}_FLAGS and DRM_TEGRA_GEM_{GET,SET}_TILING
    IOCTLs were badly designed and have since been obsoleted by framebuffer
    modifiers. Remove these implementations to make it clear their usage is
    discouraged.
