This isn't the normal way to break up a line.  It might even cause
problems if you run with checkpatch.pl --strict.  And anyway this fits
on one line:

	return gasket_is_extended_dev_addr_bad(pg_tbl, dev_addr, num_pages);

But normally we would do:

	return gasket_is_extended_dev_addr_bad(pg_tbl, dev_addr, num_pages,
					       wha'ever, blah, blah, blah);

There are times when that looks a bit ugly if the variable names are
long so we could do:

	return gasket_is_extended_dev_addr_bad(
				long_variable_name_asdfasdfaasdf,
				pg_tbl, dev_addr);

But generally try to get a couple tabs in from the start of the function
name.
