lib/vsprintf: declare no_hash_pointers in sprintf.h
Sparse is not happy to see non-static variable without declaration:
lib/vsprintf.c:61:6: warning: symbol 'no_hash_pointers' was not declared.
Should it be static?
Declare respective variable in the sprintf.h. With this, add a comment to
discourage its use if no real need.
