iio: proximity: lidar: correct return value

mranostay · jic23 · commit 9979e320b559 · 2016-01-03T17:54:08.000Z
lidar_i2c_xfer() function was never a non-positive value on error, and this correct that with a -EIO return code. Fixes: 366e656 ("iio: proximity: lidar: optimize i2c transactions") Signed-off-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
