This message is wrong.  Also it isn't needed because kzalloc() prints
its own more complete message.

Also unlikely() isn't needed here in the attach function.  Likely and
unlikely hints only belong in the fast path, and generally shouldn't
be included in driver code (only in core kernel code).

Don't resend the patch obviously since this was there in the
original code.
