From 6243d38fc0775e9dc1a38835aef55efb273ac4d5 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Sun, 22 Oct 2017 14:43:33 -0700 Subject: drivers/memstick: 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.
