[net-next v2 0/8] net: convert tasklets to use new

[Allen Pais]

From: Allen Pais <apais@linux.microsoft.com>

Commit 12cc923f1ccc ("tasklet: Introduce new initialization API")'
introduced a new tasklet initialization API. This series converts
all the net/* drivers to use the new tasklet_setup() API

The following series is based on net-next (9faebeb2d)

v1:
  fix kerneldoc

[net-next v2 1/8] net: dccp: convert tasklets to use new tasklet_setup() API

[Allen Pais]

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.
