From c97f8169fb227cae5adeac56cafa980f25978031 Mon Sep 17 00:00:00 2001 From: Haren Myneni Date: Thu, 31 Aug 2017 00:11:29 -0700 Subject: [PATCH] crypto/nx: Rename nx842_powernv_function as icswx function Rename nx842_powernv_function to nx842_powernv_exec. nx842_powernv_exec points to nx842_exec_icswx and will be point to VAS exec function which will be added later for P9 NX support.
