Subject[PATCH] [125/139] mv_xor: fix race in tasklet function
Date
2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Saeed Bishara <saeed@marvell.com>

commit 8333f65ef094e47020cd01452b4637e7daf5a77f upstream.

use mv_xor_slot_cleanup() instead of __mv_xor_slot_cleanup() as the former function
aquires the spin lock that needed to protect the drivers data.
