From 20b135e48cdda7a7dfccef7286def66e5c9686c3 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 5 Aug 2020 12:52:07 +0300 Subject: cifs: Fix an error pointer dereference in cifs_mount() The error handling calls kfree(full_path) so we can't let it be a NULL pointer. There used to be a NULL assignment here but we accidentally deleted it. Add it back.
