media: i2c: imx219: Simplify code handling in s_fmt

Jacopo Mondi · mchehab · commit 34e3d3c9ddbd · 2023-08-10T07:58:39.000+02:00
The imx219_set_pad_format() function adjusts the media bus code provided
through the v4l2_subdev_format parameter to a media bus code known
to be supported by the sensor.

The same exact operation is performed by the imx219_get_format_code()
function which called by imx219_update_pad_format(), which is in the
imx219_set_pad_format() call path.

Remove the duplicated operation and simplify imx219_set_pad_format().
