From 08237974af22a97da59869979ef1a515524d5cc3 Mon Sep 17 00:00:00 2001 From: Lin Ming Date: Fri, 8 Aug 2008 11:57:11 +0800 Subject: [PATCH] ACPI: replace AE_BAD_ADDRESS exception code with AE_ERROR The AE_BAD_ADDRESS exception code is now unused in ACPICA. For linux, it's only used at wmi.c and acer-wmi.c. I checked both wmi.c and acer-wmi.c, the AE_BAD_ADDRESS exception code has no special meaning. The parent functions just call AE_SUCCESS() or AE_FAILURE() to check the return status. So it's safe to replace AE_BAD_ADDRESS with AE_ERROR.
