Title
memory: renesas-rpc-if: fix possible NULL pointer dereference of resource
Summary
In the Linux kernel, the following vulnerability has been resolved: memory: renesas-rpc-if: fix possible NULL pointer dereference of resource The platform_get_resource_byname() can return NULL which would be immediately dereferenced by resource_size(). Instead dereference it after validating the resource. Addresses-Coverity: Dereference null return value
