checkpatch: macros which define structure members are not complex
Andy Whitcroft [Thu, 16 Oct 2008 05:02:31 +0000 (22:02 -0700)]
We often see macros which define structure members, these are not complex
and necessarily do not have braces or brackets.  For example:

    #define _PLIST_HEAD_INIT(head)                      \
        .prio_list = LIST_HEAD_INIT((head).prio_list),  \
        .node_list = LIST_HEAD_INIT((head).node_list)
