Subject: [PATCH 02/58] net/lapb: Convert timers to use timer_setup()
Date: Mon, 16 Oct 2017 17:28:46 -0700 [thread overview]
Message-ID: <1508200182-104605-3-git-send-email-keescook@chromium.org> (raw)
In-Reply-To: <1508200182-104605-1-git-send-email-keescook@chromium.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.
