Cute.  Eric, can you please suggest what we should do here?

Yes, the ENOMEM is bogus.  But irda_sysctl_register() saw a NULL return
from register_sysctl_table() and simply has no clue why it failed, and is
forced to assume ENOMEM.  That's a design shortcoming in
register_sysctl_table(), whcih should have returned an ERR_PTR.  Doesn't
matter much.
