Blackfin SPI Driver: use len_in_bytes when we care about the number of bytes transferred
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) Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bryan Wu <cooloney@kernel.org> Acked-by: David Brownell <dbrownell@users.sourceforge.net> Cc: David Brownell <david-b@pacbell.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
