Subject: [PATCH v2 05/26] lib/dma-noop: Clarify a comment
Date: Thu, 12 Jan 2017 11:06:57 -0800 [thread overview]
Message-ID: <20170112190718.6728-6-bart.vanassche@sandisk.com> (raw)
In-Reply-To: <20170112190718.6728-1-bart.vanassche@sandisk.com>
The next patch in this series will introduce another set of DMA
operations that map 1:1 with memory. Clarify that dma-noop maps
to physical addresses.
