Subject: media: i2c: video-i2c: Convert enum->pointer for data in the match
tables
Author: Biju Das <biju.das...@bp.renesas.com>
Date: Sun Aug 20 08:58:46 2023 +0100
Convert enum->pointer for data in the match tables, so that
device_get_match_data() can do match against OF/ACPI/I2C tables, once i2c
bus type match support added to it.
Replace enum->struct *video_i2c_chip for data in the match table. Simplify
the probe() by replacing device_get_match_data() and ID lookup for
retrieving data by i2c_get_match_data().
