[ Upstream commit d461873272169a3fc3a8d155d7b1c92e9d97b419 ]
The offset inside the fragment was not used for the dma address and
silent data corruption resulted because TSO makes the checksum match.

The of_node_put() function tests whether its argument is NULL
and then returns immediately.
Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
