From 846d0c6f794c4bef90a021b18cedde598758507c Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Mon, 16 Oct 2017 16:43:25 -0700 Subject: s390/cio: 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.
