This is correct for OTG hosts, where either SRP or -an ID interrupt could turn VBUS on again. - -However, for non-OTG hosts there's no way to turn VBUS on again, -so the host becomes unusable. And the procfs entry which once -allowed a manual workaround for this is now gone. - -This patch adds an is_otg_enabled() check before scheduling the -switch-off timer in disconnect path, supporting a "classic host" -mode where SRP is unavailable. - -[ dbrownell-Rn4VEauK+AKRv+LV9MX5uipxlwaOVQ5f@public.gmane.org: tweak patch description ] - -Signed-off-by: Ajay Kumar Gupta <ajay.gupta-l0cyMroinI0@public.gmane.org> -Signed-off-by: David Brownell <dbrownell-Rn4VEauK+AKRv+LV9MX5uipxlwaOVQ5f@public.gmane.org> -Signed-off-by: Greg Kroah-Hartman <gregkh-l3A5Bk7waGM@public.gmane.org> ---- - drivers/usb/musb/musb_core.c | 2 +- - 1 files changed, 1 insertions(+), 1 deletions(-) - -diff --git a/drivers/usb/musb/musb_core.c b/drivers/usb/musb/musb_core.c -index af77e46..338cd16 100644 ---- a/drivers/usb/musb/musb_core.c -+++ b/drivers/usb/musb/musb_core.c -@@ -769,7 +769,7 @@ static irqreturn_t musb_stage2_irq(struct musb *musb, u8 int_usb, - case OTG_STATE_A_SUSPEND: - usb_hcd_resume_root_hub(musb_to_hcd(musb)); - musb_root_disconnect(musb); -- if (musb->a_wait_bcon != 0) -+ if (musb->a_wait_bcon != 0 && is_otg_enabled(musb)) - musb_platform_try_idle(musb, jiffies - + msecs_to_jiffies(musb->a_wait_bcon)); - break; --- -1.6.0.4 - |
