[PATCH] tty: metag_da: Convert timers to use timer_setup()

From: Kees Cook
Date: Mon Oct 16 2017 - 19:28:43 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.
