[PATCH 3/3] acpi: Kill macro INVALID_TABLE().
The macro INVALID_TABLE() is defined like this: #define INVALID_TABLE(x, path, name)\ { pr_err("ACPI OVERRIDE: " x " [%s%s]\n", path, name); continue; } And it is used like this: for (...) { ... if (...) 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.
