From 02839a8b51002d90e4b7c52bf37531834b063f71 Mon Sep 17 00:00:00 2001 From: Dave Jiang Date: Thu, 24 Feb 2011 17:45:57 -0800 Subject: [PATCH] isci: copy the oem parameters instead of assign Since the data structure for oem from orom/efi/firmware is the same as what the core uses, we can just do a direct copy instead of assignment.
