INVALID_TABLE() ... } The "continue" in the macro makes the code hard to understand. And also, this macro is only used several times in a single file. As suggested by Joe Perches , we can remote it and use pr_err directly. So after this patch, this macro is removed, and pr_err() is used like this: for (...) { ... if (...) { pr_err("ACPI OVERRIDE: ......"); continue; } ... } Signed-off-by: Tang Chen Suggested-by: Joe Perches Acked-by: Tejun Heo Acked-by: Rafael J.
