From 77c24888b7693eecee904308e0ee51f7f1f564df Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 21 Sep 2009 19:29:30 +0000 Subject: [PATCH] ACPI: remove unnecessary argument checking acpi_add_single_object() is static, and all callers supply a valid "child" argument, so we don't need to check it. This patch also remove some unnecessary initializations.
