From 57f9616b79549e772cf4dd3aa1d2df5b6c8acdfa Mon Sep 17 00:00:00 2001 From: Dan Carpenter <dan.carpenter@oracle.com> Date: Tue, 12 Jun 2012 19:28:50 +0300 Subject: ideapad: uninitialized data in ideapad_acpi_add() We only initialize the high bits of "cfg". It probably doesn't cause a problem given that this is platform specific code and doesn't have to worry about endianness etc. But it's sort of messy.
