The platform_get_irq() function returns negative if an error occurs. zero or positive number on success. platform_get_irq() error checking for zero is not correct. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> --- changes in v2 : irq was unsigned. so using signed variable ret. changes in v3 : Add failure case '<= 0' instead of '< 0'. IRQ0 is not valid. changes in v4 : Return -ENODEV insted of irq. sound/soc/nuc900/nuc900-ac97.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
