Why would you do this? It's insane. kasprintf() is not the right thing
at all to use for anything like this. It appears that you want to use
strncpy() or something. Or you could just avoid the extra copy
entirely in 99% of all cases and just use simple_strtol() and check
that the end didn't overflow the substring, which it presumably never
does anyway.

Yes, the stupid code is already disgustingly bad. But let's not make
it *worse*, for chrissake!
