Sorry, no. I don't like this. This driver is a very primitive piece of
code, allowing you to bootstrap a camera in a most simple static way. We
even were considering removing it from the kernel, because there's only
one user currently in the mainline and, unfortunately, it is not very well
maintained. So, you can use this driver as it is in the kernel now,
bug-fixes are welcome. But if it isn't enough for you, this means you need
a proper driver.
Thanks
