Subject: [PATCH 11/12] of: Move setting of pointer to beside test for non-null

From: Frank Rowand <frank.rowand@...sony.com>

Value of pointer was calculated in an earlier block than
where it was used.  Move it down into the block where it
is used, immediately before where is is checked to be valid.
