From c22d5dcd7a8ee8316dfbad66d13abb6d661c86b9 Mon Sep 17 00:00:00 2001 From: Bandan Das Date: Wed, 23 Dec 2015 14:39:46 +0530 Subject: [PATCH] usb-mtp: use safe variant when cleaning events list usb_mtp_inotify_cleanup uses QLIST_FOREACH to pick events from a list and free them which is incorrect. Use QLIST_FOREACH_SAFE instead.
