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 value of 0 and the SPI bus driver passes them unaltered to client device drivers.

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

Have all architectures removed 0 as a valid IRQ?
