checkpatch: high precedence operators do not require additional parentheses in #defines
With any very high precedence operator it is not necessary to enforce additional parentheses around simple negated expressions. This prevents us requesting further perentheses around the following: #define PMEM_IS_FREE(id, index) !(pmem[id].bitmap[index].allocated) For now add logical and bitwise not and unary minus.
