It's documented here:
http://linuxtv.org/downloads/v4l-dvb-apis/func-poll.html

It checks if POLLERR flag is set on the poll structure. If it's the case, it
means there was a fatal error reported by the driver. Normal procedure is to
stop any operation and start again. Your driver should not set this flag unless
it's it's in trouble and can't recover.
