iio: adc: checking for NULL instead of IS_ERR() in probe
mcb_request_mem() returns an ERR_PTR(), it doesn't return NULL. Fixes: 74aeac4da66f ('iio: adc: Add MEN 16z188 ADC driver') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org> Cc: Stable@vger.kernel.org
