IRQ lookup functions such as those in ACPI can return error values when
an IRQ is not defined. The i2c core driver converts the error codes to a

The cs35l56 driver should only accept positive non-zero values as IRQ
numbers.

Mark, I don't understand what your objection is.
What is it you want us to do to get this bugfix accepted?
