Subject: [PATCH] net/mlx4_core: Convert timers to use timer_setup()
Date: Wed, 4 Oct 2017 17:51:54 -0700 [thread overview]
Message-ID: <20171005005154.GA23500@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.

This requires commit 686fef928bba ("timer: Prepare to change timer
callback argument type") in v4.14-rc3, but should be otherwise
stand-alone.
