From da1cad7342a14c7027d95e361878b3442f1d93ad Mon Sep 17 00:00:00 2001 From: Allen Pais Date: Tue, 3 Nov 2020 14:48:18 +0530 Subject: [PATCH] net: mac80211: 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.
