From 40edc9813b9bc5d7628b821f1dad7fc87e101066 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Mon, 10 Feb 2014 20:00:26 -0300 Subject: [PATCH] watchdog: orion: Remove unneeded BRIDGE_CAUSE clear After adding the IRQ request, the BRIDGE_CAUSE bit should be cleared by the bridge interrupt controller. There's no longer a need to do it in the watchdog driver, so we can simply remove it.
