From mboxrd@z Thu Jan 1 00:00:00 1970 From: Kees Cook Subject: [PATCH] libata: Convert timers to use timer_setup() Date: Wed, 4 Oct 2017 17:48:42 -0700 Message-ID: <20171005004842.GA23011@beast> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Content-Disposition: inline Sender: linux-kernel-owner@vger.kernel.org To: linux-kernel@vger.kernel.org Cc: Tejun Heo , linux-ide@vger.kernel.org, Thomas Gleixner List-Id: linux-ide@vger.kernel.org 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.
