+Subject: usb: cdnsp: do not disable slot for disabled slot

+From: Peter Chen <peter.chen@cixtech.com>
+
+commit 7e2c421ef88e9da9c39e01496b7f5b0b354b42bc upstream.
+
+It doesn't need to do it, and the related command event returns
+'Slot Not Enabled Error' status.

+Subject: usb: dwc3: Abort suspend on soft disconnect failure
+
+From: Kuen-Han Tsai <khtsai@google.com>
+
+commit 630a1dec3b0eba2a695b9063f1c205d585cbfec9 upstream.
+
+When dwc3_gadget_soft_disconnect() fails, dwc3_suspend_common() keeps
+going with the suspend, resulting in a period where the power domain is
+off, but the gadget driver remains connected. Within this time frame,
+invoking vbus_event_work() will cause an error as it attempts to access
+DWC3 registers for endpoint disabling after the power domain has been
+completely shut down.
+
+Abort the suspend sequence when dwc3_gadget_suspend() cannot halt the
+controller and proceeds with a soft connect.

+
+Flush dbc requests when dbc is stopped and transfer rings are freed.
+Failure to flush them lead to leaking memory and dbc completing odd

+
+commit 2b857d69a5e116150639a0c6c39c86cc329939ee upstream.
+
+When /dev/ttyDBC0 device is created then by default ECHO flag
+is set for the terminal device. However if data arrives from
+a peer before application using /dev/ttyDBC0 applies its set
+of terminal flags then the arriving data will be echoed which
+might not be desired behavior.
