iio: proximity: lidar: correct return value
lidar_i2c_xfer() function was never a non-positive value on error, and this correct that with a -EIO return code. Fixes: 366e65633cf4 ("iio: proximity: lidar: optimize i2c transactions") Signed-off-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
