However, it would be hard to # avoid for a PCI crypto driver using async probing. # # In this particular call trace, the problem is easily avoided because # the only reason the module is being requested during probing is the # add_early_randomness call in the hwrng core. This feature is # vestigial since there is now a kernel thread dedicated to doing # exactly this. # # So remove add_early_randomness as it is no longer needed. # # Reported-by: Nícolas F. R. A.
