Subject: [PATCH 4/4] net: macb: add remove callback
Date: Fri,  2 Nov 2018 08:26:32 +0100	[thread overview]
Message-ID: <20181102072632.10654-4-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20181102072632.10654-1-s.hauer@pengutronix.de>

The macb driver does DMA and thus should be quiesced on shutdown. Add
the remove callback.
