From 6537ae2f20412dd1c7464272dfff77d5afb50d25 Mon Sep 17 00:00:00 2001 From: Tomas Winkler Date: Fri, 27 Jan 2017 16:32:43 +0200 Subject: [PATCH] mei: amthif: clean command queue upon disconnection In order to prevent memory leak clean up the amthif command queue upon disconnection. The issue may happen only on error path as the command queue is cleaned upon file descriptor close. And remove the cleanup from mei_cl_flush_queues as this code is never reached for amthif client.
