[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.
