Re: [PATCH 07/11] dmaengine: at_hdmac: add a few const qualifiers

From: Nicolas Ferre <hidden>
Date: 2012-07-13 13:54:27
Also in: linux-arm-kernel

From: Uwe Kleine-König <redacted>

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
