Subject: [PATCH] mips/jazz: provide missing dma_mask/coherent_dma_mask
Date: Thu, 12 Jul 2018 15:42:55 +0200 [thread overview]
Message-ID: <20180712134255.30748-1-tbogendoerfer@suse.de> (raw)
Commit 205e1b7f51e4 ("dma-mapping: warn when there is no coherent_dma_mask")
introduced a warning, if a device is missing a coherent_dma_mask.
ESP and sonic are using dma mapping functions, so they need dma masks.
