Subject: [PATCH 04/20] Blackfin SPI Driver: use len_in_bytes when we care about the number of bytes transferred

From: Mike Frysinger <vapier.adi@...il.com>

Use len_in_bytes when we care about the number of bytes transferred
rather than the number of spi transactions. (this value will be the
same for 8bit transfers, but not any other sizes)
