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 <nfont at linux.vnet.ibm.com> (supporter:IBM Power 842 com...)
Marcelo Henrique Cerri <mhcerri at linux.vnet.ibm.com> (supporter:IBM Power in-Nest...)

"David S. Miller" <davem at davemloft.net> (maintainer:CRYPTO API)
linux-crypto at vger.kernel.org (open list:IBM Power in-Nest...)
linux-kernel at vger.kernel.org (open list)

If any of the above is out of date please send me a patch for MAINTAINERS.
