Wrong coding style, the openning brace should be on the same line
as the if() check, see Documentation/CodingStyle Your email
client has also corrupted the tab characters into spaces, making
the patch unusable even if it were correct.
Next, if you are going to do this, you should modify aarp_proto_init()
to return error values, so that atalk_init() can see it and thus
undo the initialization it does and return an error for the module
load.
It is not useful to add error checks, without propagating them,
because an OOPS is just as good as a partially-initialized protocol
since that is likely to crash or malfunction as well.
The protocol is thus equally broken before and after your changes.
Please completely implement this fix, thank you.
