[PATCH 08/35] dma: imx-dma: convert tasklets to use new tasklet_setup() API

From: Allen Pais
Date: Mon Aug 17 2020 - 04:19:13 EST


In preparation for unconditionally passing the
struct tasklet_struct pointer to all tasklet
callbacks, switch to using the new tasklet_setup()
and from_tasklet() to pass the tasklet pointer explicitly.
