It "looks" unused, But thanks to the obscurity of CPP macros using ## to
concatenate tokens it is needed.
This harmless looking line:
define_id_show_func(ppin, "%llx");
is transmogrified by this:
#define define_id_show_func(name, fmt) \
static ssize_t name##_show(struct device *dev, \
struct device_attribute *attr, char *buf) \
{ \
return sysfs_emit(buf, fmt "\n", topology_##name(dev->id)); \
^^^^^^^^^^^^^^^
This becomes topology_ppin
}
Will fix the other stuff and rebase to latest so part 4 applies.
Thanks for the review.
-Tony
