[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. Biederman <ebiederm@xmission.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
