====================
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:

The third one replaces the driver's current broken endpoint lookup
helper, which could end up accepting incomplete interfaces and whose
