From fd7b673c92731fc6c0b1e999adfd87b6762ee797 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Fri, 16 Mar 2012 09:14:00 +0100 Subject: watchdog: Add support for WDIOC_GETTIMELEFT IOCTL in watchdog core This patch adds support for WDIOC_GETTIMELEFT IOCTL in watchdog core. So, there is another function pointer added to struct watchdog_ops, which can be passed by drivers to support this IOCTL. Related documentation is updated too.
