From 83dc9fecd5d4c84e9405c91098ae9dc07c201b90 Mon Sep 17 00:00:00 2001 From: Jisheng Zhang Date: Tue, 2 Jun 2015 18:38:35 +0800 Subject: [PATCH] mmc: sdhci-pxav3: fix device wakeup initialization MMC_PM_KEEP_POWER doesn't imply MMC_PM_WAKE_SDIO_IRQ, we should only enable device wake up when MMC_PM_WAKE_SDIO_IRQ is set. And "pm_flags" is the requested pm features, we should not set it in the host driver. At the same time, device wakeup is disabled by default, so there's no need to disable device wakeup explicitly. This patch fixes the warning as following: [ 64.616651] ------------[ cut here ]------------ [ 64.616665] WARNING: CPU: 0 PID: 79 at linux/kernel/irq/manage.c:603 irq_set_irq_wake+0xf0/0x11c() [ 64.616667] Unbalanced IRQ 87 wake disable Signed-off-by: Jisheng Zhang Signed-off-by: Ulf Hansson --- drivers/mmc/host/sdhci-pxav3.c | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-) diff --git a/drivers/mmc/host/sdhci-pxav3.c b/drivers/mmc/host/sdhci-pxav3.c index 01cb2d309a6a..9cd5fc62f130 100644 --- a/drivers/mmc/host/sdhci-pxav3.c +++ b/drivers/mmc/host/sdhci-pxav3.c @@ -457,12 +457,8 @@ static int sdhci_pxav3_probe(struct platform_device *pdev) platform_set_drvdata(pdev, host); - if (host->mmc->pm_caps & MMC_PM_KEEP_POWER) { + if (host->mmc->pm_caps & MMC_PM_WAKE_SDIO_IRQ) device_init_wakeup(&pdev->dev, 1); - host->mmc->pm_flags |= MMC_PM_WAKE_SDIO_IRQ; - } else { - device_init_wakeup(&pdev->dev, 0); - } pm_runtime_put_autosuspend(&pdev->dev); -- 2.20.1
