  This patch eliminates a lot of warnings like this on old kernels:

media_build/v4l/au8522_decoder.c:842: warning: data definition has no type or storage class
media_build/v4l/au8522_decoder.c:842: warning: type defaults to 'int' in declaration of 'module_i2c_driver'
media_build/v4l/au8522_decoder.c:842: warning: parameter names (without types) in function declaration
media_build/v4l/au8522_decoder.c:832: warning: 'au8522_driver' defined but not used

Tested with 2.6.32 and 3.3-rc6 without problems.
