From b5f0a3bfc11f04b2991355a71943fd0c4534869a Mon Sep 17 00:00:00 2001 From: Allen Pais Date: Mon, 14 Sep 2020 12:59:37 +0530 Subject: [PATCH] qed: 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.
