Gal Pressman 674e318089 net: Fix undefined behavior in netdev name allocation ... Cited commit removed the strscpy() call and kept the snprintf() only. It is common to use 'dev->name' as the format string before a netdev is registered, this results in 'res' and 'name' pointers being equal. According to POSIX, if copying takes place between objects that overlap as a result of a call to sprintf() or snprintf(), the results are undefined. Add back the strscpy() and use 'buf' as an intermediate buffer.
