From 5c23c9078f8e3476982409b1075b54c8cd65e82c Mon Sep 17 00:00:00 2001 From: Anand Gadiyar Date: Sat, 21 Feb 2009 15:31:40 -0800 Subject: [PATCH] USB: musb: resume suspended root hub on disconnect If this is not done, khubd will not be informed of the disconnect and will assume the device is still there. Easily seen when a hub is connected with no device attached to it; it will autosuspend. When the hub is disconnected, it still shows up in /proc/bus/usb/devices Signed-off-by: Anand Gadiyar Acked-by: Felipe Balbi Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman --- drivers/usb/musb/musb_core.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/usb/musb/musb_core.c b/drivers/usb/musb/musb_core.c index b120fdcd8894..60cbaec1aa41 100644 --- a/drivers/usb/musb/musb_core.c +++ b/drivers/usb/musb/musb_core.c @@ -767,6 +767,7 @@ static irqreturn_t musb_stage2_irq(struct musb *musb, u8 int_usb, #ifdef CONFIG_USB_MUSB_HDRC_HCD case OTG_STATE_A_HOST: case OTG_STATE_A_SUSPEND: + usb_hcd_resume_root_hub(musb_to_hcd(musb)); musb_root_disconnect(musb); if (musb->a_wait_bcon != 0) musb_platform_try_idle(musb, jiffies -- 2.20.1
