Subject: [PATCH 3.18 61/68] message: i2o: fix 64bit build warnings

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

It seems that most of the 64bit build warnings were fixed up in this
driver, but 2 were forgotten.  This code is long deleted from newer
kernels, so the fix is not needed there, but make it here in the 3.18
tree to keep the build quiet.
