I didn't overwrite the previous bug fix that existed in the uboot...
The commit you point out is still there in lib/zlib/inffast.c

What I am doing is just adding, not subtracting, nor overwriting...
This patch set change is not to updating the zlib version...
The previous inflate related stuff in uboot code is kept untouched.
