Broken controls with V4L2 and the saa7134 driver

[Billy Biggs <vektor@xxxxxxxxxxxx>]

  I have a user who's having what seems to be random things
fail with the saa7134 driver.  The full bug report is here:

  https://sourceforge.net/tracker/index.php?func=detail&aid=809153&group_id=64301&atid=506987

  The user is using saa7134-0.2.8 on kernel 2.4.22 and using
v4l2-20030826.  Is there maybe some incompatibility here?

  They're having S_CTRL fail for the mute setting with EINVAL,
which does not seem to make sense by my reading of the source
code.

  Gerd, do you have any advice?

  Thanks,
