Subject: [PATCH] drm: gma500: Convert timers to use timer_setup()
Date: Tue, 24 Oct 2017 08:16:09 -0700	[thread overview]
Message-ID: <20171024151609.GA104501@beast> (raw)

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.
