Subject: [PATCH 10/10] sound: ua101: convert tasklets to use new tasklet_setup() API

From: Allen Pais <[email-masked]>
Date: Mon, 17 Aug 2020 14:27:03 +0530

From: Allen Pais <[email-masked]>

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.
