From 032cfd66afcc2dd2c7be89c71b020fcb15bcc37d Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 25 Oct 2017 03:53:59 -0700 Subject: [PATCH] drivers/net: wan/sdla: 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.
