There is more to be confused about -- you don't get the host/device connection interrupt from the PHY, but you dig one of them from the EHCI host and the other from the EHCI host too -- which is pretty messed up already. We can certainly use IRQF_SHARED to trap some of the interrupts in the PHY code, but that's still quite weird. > Sascha Best regards, Marek Vasut -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
