Hello,
This patch set modifies the vb2 implementation of the poll() operation to set
the POLLERR flag for fatal errors only. The rationale and implementation
details are explained in the individual commit messages.

When a fatal error occurs in the pipeline signal it to the vb2 queue
with a call to vb2_queue_error(). The queue will then take care to
return -EIO when preparing buffers, remove the driver-specific code that
now duplicates that check.

Hi James,
The first basic thing you should look at is if the dvb device has got all
its pieces.
A dvb adapter has, sort of, 4 sub-devices:
