Subject: [PATCH] powerpc/watchdog: Convert timers to use timer_setup()
Date: Mon, 16 Oct 2017 16:47:10 -0700	[thread overview]
Message-ID: <20171016234710.GA102273@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.
