lib/vsprintf: split out sprintf() and friends
Patch series "lib/vsprintf: Rework header inclusions", v3.
Some patches that reduce the mess with the header inclusions related to
vsprintf.c module. Each patch has its own description, and has no
dependencies to each other, except the collisions over modifications of
the same places. Hence the series.
This patch (of 2):
kernel.h is being used as a dump for all kinds of stuff for a long time.
sprintf() and friends are used in many drivers without need of the full
kernel.h dependency train with it.
Here is the attempt on cleaning it up by splitting out sprintf() and
friends.
