[PATCH] staging/irda/bfin_sir: Convert timers to use timer_setup()

From: Kees Cook
Date: Wed Oct 18 2017 - 16:23:50 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.
