Re: joystick GetDeviceData patch

The device.c part of this patch is probably not supposed be included.
The rest seems OK, except for a couple of things.

1. I'm wondering if the overflow flag really should be cleared when the
app is just peeking with DIGDD_PEEK now? You had it differently in your
previous version of the patch?

2. You seem to be removing the joy_polldev() call from GetDeviceData. I
don't think you should. For Linux 2.2, 2.4, and 2.6, the device is not
really a polled device, so we do not specify the DIDOI_POLLED flag.
There's a chance some games may actually honor this flag properly, by
not calling Poll when it's absent, and these would not work if you
remove the call.

By the way, there's a bug in joy_polldev, where the GEN_EVENT macro is
fed the original dwData from the device driver, instead of the
range-adjusted value (dwOut) which was written to
This->buffer+odf->dwOfs. Feel free to fix it. It could even be related
to your axis problem.
