Subject[PATCH 5.10 061/103] iio: dac: ti-dac5571: fix an error code in probe()
Date
From: Dan Carpenter <dan.carpenter@oracle.com>

commit f7a28df7db84eb3410e9eca37832efa5aed93338 upstream.

If we have an unexpected number of channels then return -EINVAL instead
of returning success.

Fixes: df38a4a72a3b ("iio: dac: add TI DAC5571 family support")
