From 57cc666d36adc7b45e37ba4cd7bc4e44ec4c43d7 Mon Sep 17 00:00:00 2001 From: Aditya Pakki Date: Sun, 14 Jun 2020 05:58:41 +0200 Subject: [PATCH] media: st-delta: Fix reference count leak in delta_run_work delta_run_work() calls delta_get_sync() that increments the reference counter. In case of failure, decrement the reference count by calling delta_put_autosuspend().
