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).
