ASoC: Blackfin: cleanup sport handling in ASoC Blackfin AC97 code
- make sport number handling more dynamic as not all Blackfins have a linear sport map starting at 0 - indexes can be macroed away too Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Cliff Cai <cliff.cai@analog.com> Signed-off-by: Bryan Wu <cooloney@kernel.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
