From 60ddc2e5c44b4b9f5fcb440065469eacbeabf5eb Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Fri, 18 Jul 2008 15:17:35 -0700 Subject: [PATCH] fastboot: convert a few non-critical ACPI drivers to async initcalls This patch converts a few non-critical ACPI drivers to async initcalls; these initcalls (battery, button and thermal) tend to take quite a bit of time (100's of milliseconds) due to the hardware they need to talk to, but are otherwise clearly non-essential for the boot process.
