6.1-stable review patch. If anyone has any objections, please let me know. ------------------ 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.
