There is no need in extra call indirection and check from impossible flow where someone tries to set namespace without prior call to devlink_alloc(). Instead of this extra logic and additional EXPORT_SYMBOL, use specialized devlink allocation function that receives net namespace as an argument. Such specialized API allows clear view when devlink initialized in wrong net namespace and/or kernel users don't try to change devlink namespace under the hood.
