From: Carlos Llamas <cmllamas@xxxxxxxxxx>
commit cb2aeb2ec25884133110ffe5a67ff3cf7dee5ceb upstream.
Add the pending proc->delivered_freeze work to the debugfs output. This
information was omitted in the original implementation of the freeze
notification and can be valuable for debugging issues.
Fixes: d579b04a52a1 ("binder: frozen notification")
