Subject: ath9k_htc: fix NULL-deref at probe

From: Johan Hovold <[email protected]>

commit ebeb36670ecac36c179b5fb5d5c88ff03ba191ec upstream.

Make sure to check the number of endpoints to avoid dereferencing a NULL-pointer or accessing memory beyond the endpoint array should a malicious device lack the expected endpoints.
