[PATCH 3.10 27/79] spi/bcm63xx: dont substract prepend length from total length

[Greg Kroah-Hartman]

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

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

From: Jonas Gorski <jogo@xxxxxxxxxxx>

commit 86b3bde003e6bf60ccb9c09b4115b8a2f533974c upstream.

The spi command must include the full message length including any
prepended writes, else transfers larger than 256 bytes will be
incomplete.
