From 8dbddf17824861f2298de093549e6493d9844835 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Sat, 27 Aug 2005 00:56:18 -0600 Subject: [PATCH] acpi_shutdown: Only prepare for power off on power_off When acpi_sleep_prepare was moved into a shutdown method we started calling it for all shutdowns. It appears this triggers some systems to power off on reboot. Avoid this by only calling acpi_sleep_prepare if we are going to power off the system. Signed-off-by: Eric W.
