[PATCH 3/3] acpi: Kill macro INVALID_TABLE().

2013-08-14 Thread Tang Chen
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;
}
...
}
