Date: Wed, 25 Oct 2017 03:21:24 -0700 From: Kees Cook <keescook@...omium.org> To: Russell King <linux@...linux.org.uk> Cc: linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: [PATCH] ARM: footbridge: 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.
