From 201b8c655f7a48563f6a0b66f9e388460a1ea611 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Tue, 24 Mar 2009 16:50:19 -0600 Subject: [PATCH] ACPI: call acpi_wakeup_device_init() explicitly rather than as initcall This patch makes acpi_init() call acpi_wakeup_device_init() directly. Previously, acpi_wakeup_device_init() was a late_initcall (sequence 7). acpi_wakeup_device_init() depends on acpi_wakeup_device_list, which is populated when ACPI devices are enumerated by acpi_init() -> acpi_scan_init(). Using late_initcall is certainly enough to make sure acpi_wakeup_device_list is populated, but it is more than necessary. We can just as easily call acpi_wakeup_device_init() directly from acpi_init(), which avoids the initcall magic.
