[PATCH] scsi: cxgbi: Convert timers to use timer_setup()

From: Kees Cook
Date: Wed Oct 25 2017 - 06:05:56 EST


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.
