Just resent cc ing linux-pm

BTW also found that

Some others are also doing the same. eg:
 
drivers/mmc/host/omap_hsmmc.c
static int __devexit omap_hsmmc_remove(struct platform_device *pdev)
{
        struct omap_hsmmc_host *host = platform_get_drvdata(pdev);
        struct resource *res;

        pm_runtime_get_sync(host->dev);
        mmc_remove_host(host->mmc);

2. drivers/usb/musb/musb_core.c

static void musb_shutdown(struct platform_device *pdev)
{
        struct musb     *musb = dev_to_musb(&pdev->dev);
        unsigned long   flags;

        pm_runtime_get_sync(musb->controller);

Anyways will wait for feedback.
