Subject: [PATCH] BACKPORT: FROMGIT: binder: add delivered_freeze to debugfs
output
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")
