Subject: [PATCH 2/6] usb/ohci-tmio: remove the HCD_DMA flag
Date: Tue,  3 Sep 2019 10:46:11 +0200	[thread overview]
Message-ID: <20190903084615.19161-3-hch@lst.de> (raw)
In-Reply-To: <20190903084615.19161-1-hch@lst.de>

This driver doesn't support normal DMA, only direct access to its
local memory.  Remove the HCD_DMA flag to properly express that fact.

Fixes: 1e4946c4412e ("usb: add a HCD_DMA flag instead of guestimating DMA capabilities")
Signed-off-by: Christoph Hellwig <hch@lst.de>
