Subject: [PATCH] drivers/net: hippi: Convert timers to use timer_setup()

From: Kees Cook <[email-masked]>
Date: Wed, 25 Oct 2017 03:51:29 -0700

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.
