We found a pattern that could create USB protocol violations for devices
which embed an I2C bus and use I2C message lengths directly. Patch 1
fixes the bug for this driver by using a quirk flag. Patch 2 is a
cleanup to remove a pattern in the driver which can also be handled with
a quirk flag.

Wolfram Sang (2):
  media: usb: hdpvr: disable zero-length read messages
  media: usb: hdpvr: use I2C core to handle only supported messages
