Subject: media: i2c: imx219: Don't store the current mode in the imx219
structure
Author: Laurent Pinchart <laurent.pinch...@ideasonboard.com>
Date: Sun Sep 24 18:33:01 2023 +0300
The mode field of the imx219 structure is only used in
imx219_init_controls(), after the probe function sets it to point to the
default mode. Use the default mode directly when initializing controls,
and drop the mode field from the imx219 structure.
