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. Signed-off-by: Christophe Leroy <redacted> --- drivers/uio/uio_fsl_elbc_gpcm.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-)
