Subject[PATCH 14/16] wireless: ralink: convert tasklets to use new tasklet_setup() API
Date
From: 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.
