From a9346abed52f08e3e0ceb66d51f527ea11698d3c Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Mon, 16 Oct 2017 15:52:31 -0700 Subject: RDMA/cxgb4: 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 and drops a redundant initialization.
