From 7c51d17c027e52ef6ccc075e31c2eb44c13e3a32 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 24 Oct 2017 02:28:29 -0700 Subject: [PATCH] rtlwifi: 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.
