From a2930e5c44951902b63f61aa3d65f4312744de39 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Mon, 16 Oct 2017 15:51:13 -0700 Subject: IB/rdmavt: 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. setup_timer() was already being called before the open-coded init_timer() and .data assignment. These are removed as well.
