For a series of fixes at tvaudio module motivated by CVE-2008-5033.

This module were written back on 2000 and weren't receiving much 
attention nowadays. The only patches lately were related to API improvements
elsewhere (like V4L2 conversion and I2C changes).

This patch series fixes a memory leak and improves the error handling inside
the driver to reduce the potential risk of security issues, properly fixing
CVE-2008-5033.

It consists of the following patches:
   - tvaudio: fix a memory leak;
   - tvaudio: instead of using a magic number, use ARRAY_SIZE;
   - tvaudio: cleanup - group all callbacks together;
   - tvtime: remove generic_checkmode callback;
   - tvaudio: add additional logic to avoid OOPS;
   - tvaudio: update initial comments;
   - tvaudio: use a direct reference for chip description;
   - Avoid writing outside shadow.bytes[] array;
   - tvaudio: Improve comments and remove a unneeded prototype;
   - tvaudio: Improve debug msg by printing something more human;
   - CVE-2008-5033: fix OOPS on tvaudio when controlling bass/treble.

Cheers,
Mauro.
