From b28bbb7362ad44806b30470408c76f17f146b99b Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Mon, 16 Oct 2017 16:25:08 -0700 Subject: staging/fwserial: 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. Also removes redundant initialization of fw transaction timer, which already gets initialized per-transaction.
