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

[Allen Pais <allen.lkml@gmail.com>]

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.
