From 003d87cbece50c2a558c954b7ce915dcc70acba7 Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Mon, 22 Jul 2013 19:17:48 -0700 Subject: [PATCH] mwifiex: move del_timer_sync(scan_delay_timer) call to fix memleak Currently it is in mwifiex_adapter_cleanup() which doesn't get called if driver initialization is failed causing memory leak. scan_delay_timer is initialized in mwifiex_register(), so it should be deleted in mwifiex_unregister(). Hence it has been moved to appropriate place. Signed-off-by: Amitkumar Karwar Signed-off-by: Bing Zhao Signed-off-by: John W.
