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

From: Kees Cook <[email-masked]>
Date: Thu, 26 Oct 2017 22:54:59 -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.
