Subject: [PATCH] usb-ehci: Any packet completion except for NAK should set the
|
|
interrupt
|
|
|
|
As clearly stated in the 2.3.2 of the EHCI spec, any time USBERRINT get
|
|
sets then if the td has its IOC bit set USBINT should be set as well.
|
|
|
|
This means that for any status except for USB_RET_NAK we should set
|
|
USBINT if the IOC bit is set.
|
|
