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 <j...@perches.com>, 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;
}
...
}
