From 2b77839b37345693c565c835179c5f6f50a0ed77 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 24 Oct 2017 02:28:45 -0700 Subject: [PATCH] iwlegacy: 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.
