BTW, can you run the v4l2-compliance utility for the two boards that use
this radio tuner?
This utility is part of the v4l-utils repository
(http://git.linuxtv.org/v4l-utils.git).
Run as 'v4l2-compliance -r /dev/radioX -v2'.
I'm sure there will be some errors/warnings (warnings regarding
G/S_PRIORITY are to be expected). But I can use it to make a patch for
2.6.40 that fixes any issues.
The output is the same for both fm801 and es1968 (see below). Seems that
there are 4 errors:
 1. multiple-open does not work
 2. something bad with s_frequency
 3. input functions are present
 4. no extended controls
Running on 2.6.38
