Subject: can: kvaser_usb: check number of channels returned by HW
From: Olivier Sobrie <[email protected]>
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.
