You can put the function call into the if to make it more compact (and
follow more closely our current style), such as:

if (FAILED(D3DX10GetImageInfoFromMemory(src_data, src_data_size, NULL,
&img_info, NULL)))
    return E_FAIL;

Similarly below.

I don't know WIC particularly well but it seems prudent to me to check
the return value of this function call.

I think you can pass the texture data directly to CreateTexture2D()
here, avoiding the separate UpdateSubresource().

> +    *texture = (ID3D10Resource *)texture_2d;

I wonder if that is supposed to be set to NULL on failure. Can you
please add a test for that?

Is this necessary? As opposed to a simple "return hr;".
