The 0 value used for INV_CHIP_ICM42600 was not working since the match in i2c/spi was checking against NULL value.

To keep this check, add a first INV_CHIP_INVALID 0 value as safe guard.

Fixes: 31c24c1e93c3 ("iio: imu: inv_icm42600: add core of new inv_icm42600 driver") Signed-off-by: Jean-Baptiste Maneyrol jean-baptiste.maneyrol@tdk.com

Applied to the fixes-togreg branch of iio.git.

Thanks,

Jonathan
