V4L/DVB (13155): uvcvideo: Add a module parameter to set the streaming control timeout
The default streaming control timeout was found by Ondrej Zary to be too low
for some Logitech webcams. With kernel 2.6.22 and newer they would timeout
during initialization unles the audio function was initialized before the
video function.
Add a module parameter to set the streaming control timeout and increase the
default value from 1000ms to 3000ms to fix the above problem.
Thanks to Ondrej Zary for investigating the issue and providing an initial
patch.
