From 34f11cd329580fe4c3e8f10081d687331fc710f3 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Mon, 16 Oct 2017 16:35:49 -0700 Subject: mac80211: Convert timers to use timer_setup() In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.
