[PATCH 33/35] dma: plx_dma: convert tasklets to use new tasklet_setup() API

From: Allen Pais <hidden>
Date: 2020-08-17 08:23:24
Also in: bpf, linux-arm-kernel, linux-mediatek, linux-tegra, lkml
Subsystem: dma generic offload engine subsystem, plx dma driver, the rest · Maintainers: Vinod Koul, Logan Gunthorpe, 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.
