It's hard to keep these drivers to compile under 2.4. because of the

ongoing i2c changes in 2.5. Because of the fact that they are already
in the kernel and won't change any more, they can be removed here
and added to the build-2.4 directory.

-    tea6420.o - i2c-driver for the tea6420 by SGS Thomson
-
-    Copyright (C) 1998-2003 Michael Hunold <michael@mihu.de>
-
-    The tea6420 is a bus controlled audio-matrix with 5 stereo inputs,
-    4 stereo outputs and gain control for each output.
-    It is cascadable, i.e. it can be found at the adresses 0x98
-    and 0x9a on the i2c-bus.
-
