From 168b5251adddb1554926cfb94f79a8a28bc6ebe5 Mon Sep 17 00:00:00 2001 From: Wim Van Sebroeck Date: Sat, 26 Dec 2009 19:13:00 +0000 Subject: [WATCHDOG] change reboot_notifier to platform-shutdown method. Platform device drivers can use the .shutdown method to handle soft shutdown's instead of reboot_notifier's.
