[PATCH 2/2] usb: webcam: Invalid size of Processing Unit Descriptor

[Pawel Laszczak]

From: Pawel Laszczak <pawell@xxxxxxxxxxx>

According with USB Device Class Definition for Video Device the
Processing Unit Descriptor bLength should be 12 (10 + bmControlSize),
but it has 11.

Invalid length caused that Processing Unit Descriptor Test Video form
CV tool failed. To fix this issue patch adds bmVideoStandards into
uvc_processing_unit_descriptor structure.
