[PATCH] uio: uio_fsl_elbc_gpcm: Replace NO_IRQ by 0

[Christophe Leroy]

NO_IRQ is used to check the return of irq_of_parse_and_map().

On some architecture NO_IRQ is 0, on other architectures it is -1.

irq_of_parse_and_map() returns 0 on error, independent of NO_IRQ.

So use 0 instead of using NO_IRQ.
