The I2C read operation in the IRQ thread may return -ENXIO when the controller has not yet provided data after asserting IRQ. IRQ assertion does not guarantee that data is immediately available on the I2C bus. In such cases, the read request may be NACKed, resulting in -ENXIO. Treat this condition as "no data available yet" and log it at debug level instead of reporting it as a read failure. This avoids misleading error messages during normal operation.
