Subject: [PATCH v2 10/10] misc: fastrpc: Add dma_mask to fastrpc_channel_ctx
Date: Fri, 2 Sep 2022 18:49:00 +0300 [thread overview]
Message-ID: <20220902154900.3404524-11-abel.vesa@linaro.org> (raw)
In-Reply-To: <20220902154900.3404524-1-abel.vesa@linaro.org>
dma_set_mask_and_coherent only updates the mask to which the device
dma_mask pointer points to. Add a dma_mask to the channel ctx and set
the device dma_mask to point to that, otherwise the dma_set_mask will
return an error and the dma_set_coherent_mask will be skipped too.
