Subject: net: ll_temac: platform_get_resource replaced by wrong function
From: Claus Hansen Ries <chr@xxxxxxxxx>
commit 3a38a829c8bc27d78552c28e582eb1d885d07d11 upstream.
The function platform_get_resource was replaced with
devm_platform_ioremap_resource_byname and is called using 0 as name.
This eventually ends up in platform_get_resource_byname in the call
stack, where it causes a null pointer in strcmp.
if (type == resource_type(r) && !strcmp(r->name, name))
It should have been replaced with devm_platform_ioremap_resource.
Fixes: bd69058f50d5 ("net: ll_temac: Use devm_platform_ioremap_resource_byname()")
