From ae6ee2fd47f76db5a1cd02c23378057bd21c2c8d Mon Sep 17 00:00:00 2001 From: James Hogan Date: Fri, 20 Feb 2015 23:45:45 +0000 Subject: [PATCH] watchdog: imgpdc: Fix default heartbeat The IMG PDC watchdog driver heartbeat module parameter has no default so it is initialised to zero. This results in the following warning during probe: imgpdc-wdt 2006000.wdt: Initial timeout out of range! setting max timeout The module parameter description implies that the default value should be PDC_WDT_DEF_TIMEOUT, which isn't yet used, so initialise it to that. Also tweak the heartbeat module parameter description for consistency.
