Hi,
these devices have a shared interrupt endpoint. For serialcore to pass
an interrupt endpoint to a subdriver, the subdriver must define and
_export_ a fitting callback. The mos7720 driver failed to do so. This led
invariably to an oops upon open. This patch fixes it. The driver is useless
without it. Please try to get this into 2.6.21 and the stable kernels that
have this driver.
Regards
Oliver
