From 78ce6a9083c4f5ac1a73aa0b614c852db2d4e982 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 24 Oct 2017 02:29:28 -0700 Subject: [PATCH] libertas: 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.
