[ Upstream commit de5e92cb5cefd2968b96075995a36e28298edf71 ]
There is two warnings reported by coccinelle:
./drivers/spi/spi-mpc512x-psc.c:493:5-13: WARNING: Unsigned expression compared with zero: mps -> irq < 0 ./drivers/spi/spi-mpc52xx-psc.c:332:5-13: WARNING: Unsigned expression compared with zero: mps -> irq < 0
The commit "208ee586f862" ("spi: mpc5xxx-psc: Return immediately if IRQ resource is unavailable") was to check whether the IRQ resource is unavailable. When the IRQ resource is unavailable, an error code is returned, however, the type of "mps->irq" is "unsigned int", causing the error code to flip. Modify the type of "mps->irq" to solve this problem.
