Subject: [RFC/PATCH 0/3] locking fixes for cx88

Hi,

Here's a possible fix based on a patch by Ben Hutchings and
corrections from Andi Huber.  Warning: probably full of mistakes (my
fault) since I'm not familiar with any of this stuff.  Untested.
Review and testing would be welcome.

  [media] cx88: fix locking of sub-driver operations
  [media] cx88: use a mutex to protect cx8802_devlist
