src/include: Add parenthesis around macros
Fix the following error found by checkpatch.pl:
ERROR: Macros with complex values should be enclosed in parentheses
False positives are detected for attribute macros. An example is:
ERROR: Macros with complex values should be enclosed in parentheses
+#define BOOT_STATE_INIT_ATTR __attribute__ ((used, section
(".bs_init")))
False positive also generated for macros for linker script files. An
example is:
ERROR: Macros with complex values should be enclosed in parentheses
+#define CBFS_CACHE(addr, size) \
+ REGION(cbfs_cache, addr, size, 4) \
+ ALIAS_REGION(cbfs_cache, preram_cbfs_cache) \
+ ALIAS_REGION(cbfs_cache, postram_cbfs_cache)
False positives generated for assembly code macros. An example is:
ERROR: Macros with complex values should be enclosed in parentheses
+#define DECLARE_OPTIONAL_REGION(name) asm (".weak _" #name ", _e" #name
)
False positive detected when macro includes multiple comma separated
values. The following code is from src/include/device/azalia_device.h:
#define AZALIA_SUBVENDOR(codec, val) \
(((codec) << 28) | (0x01720 << 8) | ((val) & 0xff)), \
(((codec) << 28) | (0x01721 << 8) | (((val) >> 8) & 0xff)), \
(((codec) << 28) | (0x01722 << 8) | (((val) >> 16) & 0xff)), \
(((codec) << 28) | (0x01723 << 8) | (((val) >> 24) & 0xff))
