Can we just update compiler.h to use typeof() and drop duplicates? (typeof() a type is a pass-thru). Totally untested: diff --git a/include/linux/compiler.h b/include/linux/compiler.h index 6f04a1d8c720..cb925b883806 100644 --- a/include/linux/compiler.h +++ b/include/linux/compiler.h @@ -347,7 +347,7 @@ static inline void *offset_to_ptr(const int *off) * Whether 'type' is a signed type or an unsigned type.
