From eb7a20a3616085d46aa6b4b4224e15587ec67e6e Mon Sep 17 00:00:00 2001 From: Li Qiang Date: Mon, 28 Nov 2016 17:49:04 -0800 Subject: [PATCH] watchdog: 6300esb: add exit function When the Intel 6300ESB watchdog is hot unplug. The timer allocated in realize isn't freed thus leaking memory leak. This patch avoid this through adding the exit function.
