3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Olivier Sobrie <olivier@xxxxxxxxx> commit 862474f8b46f6c1e600d4934e40ba40646c696ec upstream. It is needed to check the number of channels returned by the HW because it cannot be greater than MAX_NET_DEVICES otherwise it will crash.
