From 6325ce1542bcee2813558e12055794b7a40d4615 Mon Sep 17 00:00:00 2001 From: Maximilian Luz Date: Fri, 4 Jun 2021 15:25:40 +0200 Subject: [PATCH] platform/surface: dtx: Add missing mutex_destroy() call in failure path When we fail to open the device file due to DTX being shut down, the mutex is initialized but never destroyed. We are destroying it when releasing the file, so add the missing call in the failure path as well.
