Subject: [PATCH 10/25] MIPS: Octeon: remove mips dma-default stubs
Date: Fri, 25 May 2018 11:20:56 +0200	[thread overview]
Message-ID: <20180525092111.18516-11-hch@lst.de> (raw)
In-Reply-To: <20180525092111.18516-1-hch@lst.de>

Octeon doesn't use the dma-default code, and now doesn't built it either,
so these stubs can be removed.
