commit 9f51ce0b9e73f83bab2442b36d5e247a81bd3401 upstream.
The return from the call to platform_get_irq() is int, it can be a negative error code, however this is being assigned to an unsigned int variable 'irqn', so making 'irqn' an int.
Eliminate the following coccicheck warning: ./drivers/gpio/gpio-mpc8xxx.c:391:5-21: WARNING: Unsigned expression compared with zero: mpc8xxx_gc -> irqn < 0
