From 9a3725631331f279fa44b6522874ce8818bcc455 Mon Sep 17 00:00:00 2001 From: Wim Van Sebroeck Date: Fri, 21 May 2010 08:11:42 +0000 Subject: [PATCH] watchdog: s3c2410_wdt - Fix removing of platform device When removing the watchdog platform device, we need to disable the access to userspace first. It makes no sense to remove the drivers clock, irq's, ... and then disable userspace access. the order of removal has also been changed so that it is the reverse of probing (this way the clock is also disabled sooner).
