[PATCH 01/16] wireless: ath5k: convert tasklets to use new tasklet_setup() API

[Allen Pais]

From: Allen Pais <allen.l...@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.
