Subject: [PATCH] rtc: destroy mutex when releasing the device
Date: Tue, 10 Nov 2020 10:42:05 +0100 [thread overview]
Message-ID: <20201110094205.8972-1-brgl@bgdev.pl> (raw)
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
Not destroying mutexes doesn't lead to resource leak but it's the correct
thing to do for mutex debugging accounting.
