[05/35] dma: dw: convert tasklets to use new tasklet_setup() API

Commit Message

Allen Aug. 17, 2020, 8:16 a.m. UTC

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.
