From 2fc5d52b212b58a5b48af19d85cb60971aa1aa4b Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Thu, 14 Jul 2011 12:53:00 +0200 Subject: [PATCH] watchdog: remove empty pm-functions While checking what watchdog drivers usually do in suspend/resume to spot common behaviour for the watchdog framework, I found these drivers which do nothing but add some cruft. Remove it, it is superfluous. New approaches should probably be done with pm_ops anyway.
