ASoC: txx9aclc: dynamically allocate dmaengine devname
Use kasprintf to allocate temporary devname string instead of a fixed size string. This fixes "FIXME" introduced on removal of BUS_ID_SIZE. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
