From 477b4c539a5c05a0ccdf11b68fdff78b2ebe56cb Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Sun, 22 Feb 2015 16:21:01 +0100 Subject: AMD Fam10h: Don't write uninitialized data into ACPI The goto statement skipped all the code that is necessary to fill in the data structures that are read right after the jump. Since there doesn't seem to be useful data, why write these ACPI objects in the first place?
