As I'm explaining there, making them obsolete without providing an alternative
was a not the best move. So, until we have no alternative and, as I pointed
out, we see the patches moving back to simple_strto*() from kstrto*(),
simple_strto*() may be used in some corner cases.

The code in charlcd.c shows a down side of people taking that "obsolete" word
too seriously. Instead of one old good function we have to replicate it many
times.

P.S. Despite the whatever decision will be made on this patch, the second one
makes sense on its own.
