Hi Dan,

Patch looks reasonable. But I can't merge it, at least not without an ACK:

$ ./scripts/get_maintainer.pl -f drivers/crypto/nx/
Nathan Fontenot <[email-masked]> (supporter:IBM Power 842 com...)
Marcelo Henrique Cerri <[email-masked]> (supporter:IBM Power in-Nest...)
Fionnuala Gunter <[email-masked]> (supporter:IBM Power in-Nest...)
Herbert Xu <[email-masked]> (maintainer:CRYPTO API)
"David S. Miller" <[email-masked]> (maintainer:CRYPTO API)
[email-masked] (open list:IBM Power in-Nest...)
[email-masked] (open list)

If any of the above is out of date please send me a patch for MAINTAINERS.

cheers
