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().

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;".

OK, I'll add more test for that.

The tests show that D3DX10CreateTextureFromMemory will always return E_FAIL on failure. See: https://source.winehq.org/git/wine.git/blob/HEAD:/dlls/d3dx10_43/tests/d3dx1...

The current tests still pass for me with just "return hr;".
