[PATCH 6/8] staging: media: zoran: fusion all modules
From: Corentin Labbe
Date: Fri Sep 03 2021 - 15:16:24 EST
The zoran driver is split in many modules, but this lead to some
problems.
One of them is that load order is incorrect when everything is built-in.
Having more than one module is useless, so fusion all zoran modules in
one.
