[PATCH] drivers/net: sis: Convert timers to use timer_setup()
From: Kees Cook <hidden>
Date: 2017-10-24 08:53:03
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.
