[PATCH] dma: Make use of the helper function devm_platform_ioremap_resource()

[PATCH] dma: Make use of the helper function devm_platform_ioremap_resource()

[cgel.zte]

From: Lv Ruyi <lv.ruyi@zte.com.cn>

Use the devm_platform_ioremap_resource() helper instead of calling
platform_get_resource() and devm_ioremap_resource() separately.

It is dmaengine: not dma:

Also add driver tag to subject line. git log would help you choosing
right tags
