From 4790b6dc7ad6c0f1eb71b94c4babe10a9c41c697 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 24 Oct 2017 03:00:10 -0700 Subject: tty: vcc: Convert timers to use timer_setup() 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.
