AFAICT this patch was originally written by Shaohui Xie.

For p3041 I thought that was only on early silicon revs that we don't
support anymore.

As for p102x, have you tested that this is actually what happens?  How
would we distinguish eLBC errors from other error sources, given that
there's no EISR0?  Do we just hope that no other error interrupts
happen?
