The driver is able to work fine without relying on a mandatory interrupt being assigned to the I2C device. This is only needed when making use of the jack-detect support.
However, the following warning message is always emitted when there is no such interrupt available:
es8316 0-0011: Failed to get IRQ 0: -22
Do not attempt to request an IRQ if it is not available/valid. This also ensures the rather misleading message is not displayed anymore.
Also note the IRQ validation relies on commit dab472eb931bc291 ("i2c / ACPI: Use 0 to indicate that device does not have interrupt assigned").
