Comment # 14 on bug 907692 from Takashi Iwai

Ah OK, I read the whole report again and understood the issue.  Sorry for the
noise.

The reported problem is basically harmless.  It's just a part of automatic load
for aes.  These modules give the same alias to "aes".  Some of modules are
hardware specific, so it returns -ENODEV at module init.  This results in such
error messages.

So, unless you really see the real problem (e.g. something doesn't work as
expected), just ignore these messages.  These are there as designed, no real
errors.  I understand this is ugly, but that's life.
