    Subject[PATCH 5.4 58/65] drm/amdgpu/atomfirmware: fix vram_info fetching for renoir
    Date
    From: Alex Deucher <alexander.deucher@amd.com>

    commit d7a6634a4cfba073ff6a526cb4265d6e58ece234 upstream.

    Renoir uses integrated_system_info table v12. The table
    has the same layout as v11 with respect to this data. Just
    reuse the existing code for v12 for stable.

    Fixes incorrectly reported vram info in the driver output.
