Crud. Ignore me. The patch is fine as-is for 6.1, 6.6, and 6.7. :(
git tag --contains f171f9e4097d ..shows that the needed patch is actually in 5.19+
Instead of using the above "git tag --contains", I was naively just running:
git grep ZCR_ELx_LEN_SIZE
..and I saw that it still came back 9 on v6.6. ...but that's because it was still set as 9 in the tools directory and I didn't notice.
Sorry for the noise. We could still do the hardcoded solution of defining it as 16 for 5.15 and older if folks want.
