Subject: [PATCH 02/10] sound: firewire: convert tasklets to use new tasklet_setup() API
From: Allen Pais <allen.lkml@...il.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.
