remove extra parentheses in return statement
fix the error reported by checkpatch: "ERROR: return is not a function, parentheses are not required" remove parentheses in return like: "return (logical expressions)" remove parentheses in return a function like: "return (rte_mempool_lookup(...))" Fixes: 6307b909b8e0 ("lib: remove extra parenthesis after return") Signed-off-by: Huawei Xie <huawei.xie@intel.com>
