[PATCH 3.12 036/107] spi/bcm63xx: dont substract prepend length from total length

From: Greg Kroah-Hartman
Date: Tue Feb 11 2014 - 15:16:35 EST


3.12-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.
