Typecasting the interrupt number from "unsigned int" to "signed int" to compare with 0(signed int by default).
Declaring interrupt number as "signed int" would violate kernel standards. So typecasting is the possible approach.
The fix is for spi-mpc52xx.

This fixes warning such as:
drivers/spi/spi-mpc52xx-psc.c:332:5-13: WARNING: Unsigned expression compared with zero: mps -> irq < 0
