guoweikang 43ca32ce12 ftrace: Fix regression with module command in stack_trace_filter ... commit 45af52e7d3b8560f21d139b3759735eead8b1653 upstream. When executing the following command: # echo "write*:mod:ext3" > /sys/kernel/tracing/stack_trace_filter The current mod command causes a null pointer dereference. While commit 0f17976568 ("ftrace: Fix regression with module command in stack_trace_filter") has addressed part of the issue, it left a corner case unhandled, which still results in a kernel crash.
