The patch titled
openpromfs: fix missing NUL
has been removed from the -mm tree. Its filename is

This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: openpromfs: fix missing NUL
From: Jan Engelhardt <jengelh@xxxxxx>
tchars is not '\0'-terminated so the strtoul may run into problems. Fix that.
Also make tchars as big as a long in hexadecimal form would take rather than
just 16.
