Subject: [PATCH net 0/3] net: lan78xx: fix NULL deref and memory leak

The first two patches fix a NULL-pointer dereference at probe that can
be triggered by a malicious device and a small transfer-buffer memory
leak, respectively.

For another subsystem I would have marked them:

	Cc: stable@...r.kernel.org	# 4.3

The third one replaces the driver's current broken endpoint lookup
helper, which could end up accepting incomplete interfaces and whose
results weren't even useeren

Johan Hovold (3):
  net: lan78xx: add missing endpoint sanity check
  net: lan78xx: fix transfer-buffer memory leak
