From 36aeebd4854c25870fa527c1f14624ac42f3658e Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Mon, 16 Oct 2017 16:24:36 -0700 Subject: [PATCH] staging: rtl8712: Convert timers to use timer_setup() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
