Subject: [PATCH v3 03/37] treewide: Consolidate set_dma_ops() implementations
Date: Fri, 20 Jan 2017 13:04:03 -0800 [thread overview]
Message-ID: <20170120210437.26389-4-bart.vanassche@sandisk.com> (raw)
In-Reply-To: <20170120210437.26389-1-bart.vanassche@sandisk.com>
Now that all set_dma_ops() implementations are identical (ignoring
BUG_ON() statements), remove the architecture specific definitions
and add a definition in <linux/dma-mapping.h>.
