From bb4ae07417c9b3be1af500a62514a2d42467cfb0 Mon Sep 17 00:00:00 2001 From: Lee Leahy Date: Tue, 7 Mar 2017 12:01:02 -0800 Subject: src/include: Add do { } while(0) around macros Fix the following error detected by checkpatch.py: ERROR: Macros with multiple statements should be enclosed in a do - while loop False positives are generated when assembly code is used in a macro. An example is: ERROR: Macros with multiple statements should be enclosed in a do - while loop +#define post_code(value) \ + movb $value, %al; \ + outb %al, $CONFIG_POST_IO_PORT False positives are also generated for linker script include files. An example is: ERROR: Macros with multiple statements should be enclosed in a do - while loop +#define SET_COUNTER(name, addr) \ + _ = ASSERT(. <= addr, STR(name overlaps the previous region!)); \ + . = addr; False positives are also generated for attribute macros.
