Subject[PATCH v1] iio: adc: MCP3564: fix the static checker warning
Date
From: Marius Cristea <marius.cristea@microchip.com>

The patch 33ec3e5fc1ea: "iio: adc: adding support for MCP3564 ADC"
from Aug 29, 2023 (linux-next), leads to the following Smatch static
checker warning:

        drivers/iio/adc/mcp3564.c:1426 mcp3564_probe()
        warn: address of NULL pointer 'indio_dev'

drivers/iio/adc/mcp3564.c
1421 struct iio_dev *indio_dev;
1422 struct mcp3564_state *adc;
1423
1424 indio_dev = devm_iio_device_alloc(&spi->dev, sizeof(*adc));
1425 if (!indio_dev) {
--> 1426 dev_err_probe(&indio_dev->dev, PTR_ERR(indio_dev),
^^^^^^^^^^^^^^^
