3.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Olivier Grenie <olivier.gre...@parrot.com>

commit d67350f8c4e67f5eba627e1fd111f16257ca9c95 upstream.

Commit 173a64cb3fcf broke support for some dib807x versions.

Fix it by providing backward compatibility with the older versions.
