[PATCH] net: ll_temac: platform_get_resource replaced by wrong function

[Claus Hansen Ries <chr@terma.com>]

From: Claus Hansen ries <chr@terma.com>

devm_platform_ioremap_resource_byname is called using 0 as name, which eventually 
ends up in platform_get_resource_byname, where it causes a null pointer in strcmp.

                if (type == resource_type(r) && !strcmp(r->name, name))

The correct function is devm_platform_ioremap_resource.

Fixes: bd69058 ("net: ll_temac: Use devm_platform_ioremap_resource_byname()")
