[PATCH 11/35] dma: ipu: convert tasklets to use new tasklet_setup() API

From: Allen Pais <hidden>
Date: 2020-08-17 08:19:44
Also in: bpf, linux-arm-kernel, linux-tegra, lkml, netdev
Subsystem: dma generic offload engine subsystem, the rest · Maintainers: Vinod Koul, Linus Torvalds

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.
