From abef751056130c90199e3bfc32916715795cde39 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 22 Aug 2017 16:38:10 -0700 Subject: [PATCH] scsi: bnx2i: 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. There was a seemingly missing call to initialize the timer in one handler, so this was added to remove the open-coded initialization. Cc: QLogic-Storage-Upstream@qlogic.com Cc: "James E.J.
