3.19.8-ckt8 -stable review patch. If anyone has any objections, please let me know.

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

From: Ellen Wang <ellen@xxxxxxxxxxxxxxxxxxx>

commit 6d00d153f00097d259f86304e11858a50a1b8ad1 upstream.

When doing an I2C_SMBUS_BYTE write (one byte write, no address),
the data to be written is in "command" not "data->byte".
