From b1466c4d248bfdbda8a88f418199d839716722fe Mon Sep 17 00:00:00 2001 From: Allen Pais Date: Wed, 2 Sep 2020 09:32:21 +0530 Subject: [PATCH] ALSA: ua101: convert tasklets to use new tasklet_setup() API 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.
