Subject: [PATCH 5/7] bcm63xx_enet: replace devm_request_and_ioremap by devm_ioremap_resource

From: Julia Lawall <Julia.Lawall@...6.fr>

Use devm_ioremap_resource instead of devm_request_and_ioremap.

This was done using the semantic patch
scripts/coccinelle/api/devm_ioremap_resource.cocci

The relevant call to platform_get_resource was manually moved down to the
call to devm_ioremap_resource.

Signed-off-by: Julia Lawall <Julia.Lawall@...6.fr>
