Signed-off-by: Arvind Yadav <arvind.yadav.cs@...il.com> --- changes in v2 : Add failure case '<= 0' instead of '< 0'. IRQ0 is not valid. changes in v3 : Return -EIO insted of ctx->irq_num. changes in v4 : Add separate error for irq == 0 and irq < 0. sound/soc/intel/atom/sst/sst_acpi.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/sound/soc/intel/atom/sst/sst_acpi.c b/sound/soc/intel/atom/sst/sst_acpi.c index 0e928d5..aec7408 100644 --- a/sound/soc/intel/atom/sst/sst_acpi.c +++ b/sound/soc/intel/atom/sst/sst_acpi.c @@ -236,6 +236,9 @@ static int sst_platform_get_resources(struct intel_sst_drv *ctx) /* Find the IRQ */ ctx->irq_num = platform_get_irq(pdev, ctx->pdata->res_info->acpi_ipc_irq_index); + if (ctx->irq_num <= 0) + return ctx->irq_num < 0 ? ctx->irq_num : -EIO; + return 0; } -- 2.7.4
