From af53b89becdcee2f15c60e6a9e951bd96d382e1c Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 11 Oct 2017 21:51:09 -0700 Subject: scsi: dc395x: 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.
