From 142d0a674d50b53366bd5ea02d7093d04960744e Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 14 Nov 2007 13:20:48 +0100 Subject: x86: fix bogus memcpy in es7000_check_dsdt() es7000_check_dst() contains a memcpy from 0, which probably should have been a memset. Remove it and check the retunr value from acpi_get_table_header.
