Darron Broad 6594690b39 V4L/DVB (9264): MFE: bugfix: multi-frontend mutual exclusion parallel open
When moving from one frontend to another
an application could spawn multiple threads opening
the same new frontend and in some circumstances all of
these could become delayed waiting for the previous
frontend readers or previous frontend writer thread to
complete.

In this scenario the first thread will succeed on open
to bring the new frontend online but any others will return
EBUSY. This is a fault.  If the first succeeds and all others
are on the same frontend then they should succeed also.
