Subject: [PATCH AUTOSEL 4.19 335/671] watchdog: rtd119x_wdt: Fix remove function
Date: Thu, 16 Jan 2020 11:59:33 -0500 [thread overview]
Message-ID: <20200116170509.12787-72-sashal@kernel.org> (raw)
In-Reply-To: <20200116170509.12787-1-sashal@kernel.org>
From: Guenter Roeck <linux@roeck-us.net>
[ Upstream commit 8dd29f19512cc75ee470d7bb8ec86af199de23a8 ]
The driver registers the watchdog with devm_watchdog_register_device() but
still calls watchdog_unregister_device() on remove. Since clocks have to
be stopped when removing the driver, after the watchdog device has been
unregistered, we can not drop the call to watchdog_unregister_device().
Use watchdog_register_device() to register the watchdog.
Fixes: 2bdf6acbfead7 ("watchdog: Add Realtek RTD1295")
