This driver can be built on arm64 but relies on NO_IRQ to check the return value of irq_of_parse_and_map() which fails to build on arm64 because the architecture does not provide a NO_IRQ. Fix this to correctly check the return value of irq_of_parse_and_map(). Even on ARM systems where the driver was previously used the check was broken since on ARM NO_IRQ is -1 but irq_of_parse_and_map() returns 0 on error. Signed-off-by:
