Subject: [PATCH 4/6] usb/max3421: remove the dummy {un, }map_urb_for_dma methods
Date: Sun, 11 Aug 2019 10:05:18 +0200 [thread overview]
Message-ID: <20190811080520.21712-5-hch@lst.de> (raw)
In-Reply-To: <20190811080520.21712-1-hch@lst.de>
Now that we have an explicit HCD_DMA flag, there is not need to override
these methods.
