Subject: Re: [PATCH 13/22] nds32: use generic dma_noncoherent_ops

Message-ID: <20180424191640.GA32495@lst.de> (raw)

Hi Greentime,

thanks for testing the patch!

It looks like nds32 doesn't have a buildbot yet, so this code didn't
even get syntax checkin, sorry.

Below is the incremental fixes based on this thread.

Can you check if my tree works if you just revert the
"nds32: use generic dma_noncoherent_ops" commit?
