Subject: [PATCH v2 26/26] IB/core: Remove ib_dma_map_*() functions
Date: Thu, 12 Jan 2017 11:07:18 -0800 [thread overview]
Message-ID: <20170112190718.6728-27-bart.vanassche@sandisk.com> (raw)
In-Reply-To: <20170112190718.6728-1-bart.vanassche@sandisk.com>
Remove the ib_dma_map_*() functions because due to previous patches
these are no longer used.
