[ARM] ARM SCSI: Don't try to dma_map_sg too many scatterlist entries
An off-by-one bug meant we were always trying to map one too many scatterlist entries. This was mostly harmless prior to the checks going in to consistent_sync(), but now causes the kernel to BUG. Also, powertec.c was missing an assignment to info->ec. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
