From d0226d315dba5e401a124b394a1af5e35e082b08 Mon Sep 17 00:00:00 2001 From: Suraj Jitindar Singh Date: Wed, 29 Jun 2016 13:38:38 +1000 Subject: powerpc/opal: Add inline function to get rc from an ASYNC_COMP opal_msg An opal_msg of type OPAL_MSG_ASYNC_COMP contains the return code in the params[1] struct member. However this isn't intuitive or obvious when reading the code and requires that a user look at the skiboot documentation or opal-api.h to verify this. Add an inline function to get the return code from an opal_msg and update call sites accordingly.
