Therefore, some macro definitions should gain additional parentheses to ensure that all current and future users will be safe with respect to expansions that can possibly alter the semantics of the passed-in macro parameter. No functional change. Signed-off-by: Nicola Vetrini Reviewed-by: Stefano Stabellini --- This patch uniforms the way these macros use parentheses, skipping the already deviated cases of the lhs of an assignment. In principle, all three could have the parentheses on the macro argument in the lhs added. --- xen/include/xen/device_tree.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/xen/include/xen/device_tree.h b/xen/include/xen/device_tree.h index 6fe2fa8b2123..e6287305a7b5 100644 --- a/xen/include/xen/device_tree.h +++ b/xen/include/xen/device_tree.h @@ -250,7 +250,7 @@ dt_find_interrupt_controller(const struct dt_device_match *matches); for ( pp = (dn)->properties; (pp) != NULL; pp = (pp)->next ) #define dt_for_each_device_node(dt, dn) \ - for ( dn = dt; (dn) != NULL; dn = (dn)->allnext ) + for ( dn = (dt); (dn) != NULL; dn = (dn)->allnext ) #define dt_for_each_child_node(dt, dn) \ for ( dn = (dt)->child; (dn) != NULL; dn = (dn)->sibling )
