From 051947b3b2a2c8487affafaf86587770e1048b78 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Mon, 16 Oct 2017 15:54:11 -0700 Subject: RDMA/cxgb3: 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 an unused timer.
