3.3-stable review patch. If anyone has any objections, please let me know.
------------------ From: Laurent Pinchart <[email protected]> commit 6f6543f53f9ce136e01d7114bf6f0818ca54fb41 upstream. The field is used to pass the UVC request data length, but can also be used to signal an error when setting it to a negative value. Switch from unsigned int to __s32.
