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 -EINVAL instead of host->irq. drivers/mmc/host/sdhci-spear.c | 4 ++++ 1 file changed, 4 insertions(+)
