From aad20cabaa3d6dfa1e0ebc8fb0537a96d3518b8f Mon Sep 17 00:00:00 2001 From: Kenji Kaneshige Date: Wed, 10 May 2006 22:20:34 +0900 Subject: [PATCH] [PATCH] acpi_pcihp: Remove improper error message about OSHP This patch converts the improper error message about OSHP evaluation to debug message which is displayed only when pci_hotplug.ko is loaded with debugging mode enabled. To do this, this patch adds a new module parameter "debug_acpi" to pci_hotplug.ko for enabling/disabling debug messages in acpi_pcihp.c.
