2022-04-04iio: dac: dac5571: Fix chip id detection for OF devicesJose Cazarin1-10/+18
When matching an OF device, the match mechanism tries all components of the compatible property. This can result with a device matched with a compatible string that isn't the first in the compatible list. For instance, with a compatible property set to compatible = "ti,dac081c081", "ti,dac5571"; the driver will match the second compatible string, as the first one isn't listed in the of_device_id table. The device will however be named "dac081c081" by the I2C core. This causes an issue when identifying the chip. The probe function receives a i2c_device_id that comes from the module's I2C device ID table. There is no entry in that table for "dac081c081", which results in a NULL pointer passed to the probe function. To fix this, add chip_id information in the data field of the OF device ID table, and retrieve it with device_get_match_data() for OF devices.
