From 14de99b44b34dbb9d0f64845b1cbb675e047767e Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 28 Aug 2018 12:13:48 +0200 Subject: watchdog: renesas_wdt: stop when unregistering We want to go into a sane state when unregistering. Currently, it happens that the watchdog stops when unbinding because of RuntimePM stopping the core clock. When rebinding, the core clock gets reactivated and the watchdog fires even though it hasn't been opened by userspace yet. Strange scenario, yes, but sane state is much preferred anyhow.
