From c7dfd0cca300c5dc49213cf1c78c77393600410d Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Thu, 1 Nov 2007 16:27:08 -0700 Subject: [WATCHDOG] spin_lock_init() fixes Some watchdog drivers initialize global spinlocks in module's init function which is tolerable, but some do it in PCI probe function. So, switch to static initialization to fix theoretical bugs and, more importantly, stop giving people bad examples.
