It's "nicer" to just put that assignment into sdw_bus_debugfs_init().

That way you just call the function, no need to return anything.

ok, thanks for the suggestion.

Same here, just pass in slave:
	sdw_slave_debugfs_exit(slave);
and have that function remove the debugfs entry in the structure.  That
way, if you are really paranoid about size, you could even drop the
debugfs structure member from non-debugfs builds without any changes to
bus.c or other non-debugfs files.

ok makes sense. will fix in v2.
