[ Upstream commit 4e8ef34e36f2839ef8c8da521ab7035956436818 ]
When work in gadget mode, currently driver doesn't update software level
link_state correctly as link state change event is not enabled for most
devices, in function dwc3_gadget_suspend_interrupt(), it will only pass
suspend event to UDC core when software level link state changes, so when
interrupt generated in sequences of suspend -> reset -> conndone ->
suspend, link state is not updated during reset and conndone, so second
suspend interrupt event will not pass to UDC core.
Remove link_state compare in dwc3_gadget_suspend_interrupt() and add a
suspended flag to replace the compare function.
Fixes: 799e9dc82968 ("usb: dwc3: gadget: conditionally disable Link State change events")
