lib: remove defining macros for strict_strto??
Open-code them rather than using defining macros. The function bodies are now next to their kerneldoc comments as a bonus. Add casts to the signed cases as they call into the unsigned versions. Avoids the sparse warnings: lib/vsprintf.c:249:1: warning: incorrect type in argument 3 (different signedness) lib/vsprintf.c:249:1: expected unsigned long *res lib/vsprintf.c:249:1: got long *res lib/vsprintf.c:249:1: warning: incorrect type in argument 3 (different signedness) lib/vsprintf.c:249:1: expected unsigned long *res lib/vsprintf.c:249:1: got long *res lib/vsprintf.c:251:1: warning: incorrect type in argument 3 (different signedness) lib/vsprintf.c:251:1: expected unsigned long long *res lib/vsprintf.c:251:1: got long long *res lib/vsprintf.c:251:1: warning: incorrect type in argument 3 (different signedness) lib/vsprintf.c:251:1: expected unsigned long long *res lib/vsprintf.c:251:1: got long long *res Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
