6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx> commit 7e8ad67c9b5c11e990c320ed7e7563f2301672a7 upstream. The failure path of allocating ei goes to a path that dereferences ei. Add another label that skips over the ei dereferences to do the rest of the clean up.
