From 53de5356be3ac62c22ae1da266943059b169d9b1 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 31 Aug 2009 22:32:20 +0000 Subject: [PATCH] ACPI: don't pass handle for fixed hardware notifications Fixed hardware devices have no handles, so just pass an explicit NULL rather than something that looks like it might be meaningful. acpi_device_notify() doesn't need the handle anyway; the only reason it takes it as an argument is because the acpi_notify_handler typedef requires it.
