4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Kristian Evensen <kristian.evensen@xxxxxxxxx> commit d1252f0237238b912c3e7a51bf237acf34c97983 upstream. The Quectel EM12 is a Cat. 12 LTE modem. It behaves in the exactly the same way as the EP06 (including the dynamic configuration behavior), so the same checks on reserved interfaces, etc. are needed.
