Subject: [PATCH 3.13 038/120] spi/bcm63xx: dont substract prepend length from total length

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

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

From: Jonas Gorski <jogo@...nwrt.org>

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.
