platform_get_irq() can fail here and we must check its return value. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> --- changes in v2 : Add failure case '<= 0' instead of '< 0'. IRQ0 is not valid. changes in v3 : Return -ENODEV insted of irq. changes in v4 : Add separate error for irq == 0 and irq < 0. sound/soc/intel/boards/mfld_machine.c | 2 ++ 1 file changed, 2 insertions(+)
