Subject: [PATCH] dmaengine: at_hdmac: add a few const qualifiers
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
This prepares of_device_id.data becoming const. Without this change
the following warning would occur:
drivers/dma/at_hdmac.c: In function 'at_dma_get_driver_data':
drivers/dma/at_hdmac.c:1228: warning: return discards qualifiers from pointer target type
