dmaengine: shdma: (cosmetic) simplify a static function
dmae_find_slave() needs only the slave_id field from the slave object, no need to pass the pointer to the object, pass the slave_id directly. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com>
