[PATCH] drm: armada: Use devm_ioremap_resource()

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

devm_request_and_ioremap() is deprecated, so use devm_ioremap_resource() 
instead.

Given the amount of patches I'm presently dealing with, I really don't
want to bother with such trivial patches at the moment.  What I do want
to do is to get stuff like imx-drm and the conversion of armada to the
component helpers out the door and queued up for 3.15 as a higher
priority than to bother with trivial stuff like this which has the
possibility to break those patches.

Let's see about dealing with this post 3.14.

Understood, thanks.

[PATCH] DRM: Armada: Use devm_ioremap_resource()

[Jingoo Han]

Use devm_ioremap_resource() because devm_request_and_ioremap() is
obsoleted by devm_ioremap_resource().

While at it, perhaps you should drop the error message too because
devm_ioremap_resource() already prints one in all failure cases.

Oh, right! It is my mistake. I will remove the error message.
Thank you for your comment.

Changes since v1:
