This whole mess should be a simpler with a table and a loop

struct edeb_filter_entry {
	u32 filenr;
	u32 filter_level;
};

# define EDEB_FILTER_ENTRY(name,nr,level) { .id = name, .filenr =  
nr, .filter_level = level }
static const struct edeb_filter_entry edeb_filter_table[] = {
	EDEB_FILTER_ENTRY("clas", 0x02, 8),
	[...]
};

Then just iterate over that table in a loop.  The end result is much  
smaller code and data, and much clearer as to intent as well.
