Subject: media: i2c: mt9v032: Extend match support for OF tables
Author: Biju Das <biju.das...@bp.renesas.com>
Date: Sun Sep 10 17:54:31 2023 +0100
The driver has an OF match table, still, it uses an ID lookup table for
retrieving match data. Currently, the driver is working on the
assumption that an I2C device registered via OF will always match a
legacy I2C device ID. The correct approach is to have an OF device ID
table using i2c_get_match_data() if the devices are registered via OF/ID.
Unify the OF/ID table by using mt9v032_model_info as match data for both
these tables and replace the ID lookup table for the match data by
i2c_get_match_data() and simplifly probe().
