Thanks! This is not actually a fixes tag, just a text to tell what
runtime errors were addressed. 

So, I'm changing the description to:

    media: uvcvideo: Increase UVC_CTRL_CONTROL_TIMEOUT to 5 seconds.
    
    Some uvc devices appear to require the maximum allowed USB timeout
    for GET_CUR/SET_CUR requests.
    
    So lets just bump the UVC control timeout to 5 seconds which is the
    same as the usb ctrl get/set defaults:
    USB_CTRL_GET_TIMEOUT 5000
    USB_CTRL_SET_TIMEOUT 5000
    
    It fixes the following runtime warnings:
       Failed to query (GET_CUR) UVC control 11 on unit 2: -110 (exp. 1).
       Failed to query (SET_CUR) UVC control 3 on unit 2: -110 (exp. 2).


in order to make it clearer.

Thanks,
Mauro
