Seems to fail the Clang build:

../../third_party/angle/src/libANGLE/renderer/d3d/d3d11/StateManager11.cpp(35,60):  error: comparison of integers of different signs: 'UINT' (aka 'unsigned int') and 'int' [-Werror,-Wsign-compare]
            maxSrvMip          = (desc.Texture2D.MipLevels == -1) ? INT_MAX : maxSrvMip;
                                  ~~~~~~~~~~~~~~~~~~~~~~~~ ^  ~~
