Subject: linux/bug.h: correct "space required before that '-'"
Correct these checkpatch.pl errors:
|ERROR: space required before that '-' (ctx:OxO)
|#37: FILE: include/linux/bug.h:37:
|+#define BUILD_BUG_ON_ZERO(e) (sizeof(struct { int:-!!(e); }))
|ERROR: space required before that '-' (ctx:OxO)
|#38: FILE: include/linux/bug.h:38:
|+#define BUILD_BUG_ON_NULL(e) ((void *)sizeof(struct { int:-!!(e); }))
I decided to wrap the bitfield expressions that begin with minus signs
in parentheses rather than insert spaces before the minus signs.
