Daniel Drake fc77786e46 uru4000: interrupt handling fixes 
This should improve driver stability somewhat. Powerup problems seem to
happen when we receive 3 unrelated interrupts while waiting for the
power-on interrupt, so let's assume that the device can only buffer 3
interrupts, and when the buffer is full, it discards new ones.

When we detect a possible buffer overflow, ask the caller to retry the
operation.

Also, saw the interrupt of death a few times, so add in a warning when
this happens. Haven't seen it since handling interrupt overflows though.

README 

libfprint
http://www.reactivated.net/fprint

libfprint is primarily licensed under the GNU LGPL. HOWEVER, THIS PRERELEASE
VERSION INCLUDES GPL CODE FROM LIBTHINKFINGER, therefore distribution is
subject to both the terms of the LGPL (see COPYING) *and* the GPL
(see COPYING.GPL).

libfprint includes code from NIST's NBIS software distribution:
http://fingerprint.nist.gov/NBIS/index.html
We include bozorth3 from the US export controlled distribution. We have
determined that it is fine to ship bozorth3 in an open source project,
see http://reactivated.net/fprint/US_export_control

At release time, I will contact libthinkfinger authors and see if they will
be happy to relicense. I expect they will.
