I think the name could be a bit better... sparse_main or ltp_checker or 
something, because a binary just called main could be confusing.

Otherwise good basis for additional checks and fixing the warnings 
emitted by sparse will allow use to raise the overall warning level.
Hopefully at some point at least "-Wall -Werror" is possible.
