[ Upstream commit 428bb001143cf5bfb65aa4ae90d4ebc95f82d007 ]
platform_get_resource_byname() may fail and in this case a NULL
dereference will occur.
Fix it to use devm_platform_ioremap_resource_byname() instead of calling
platform_get_resource_byname() and devm_ioremap().
This is detected by Coccinelle semantic patch.
