commit ca91fd8c7643d93bfc18a6fec1a0d3972a46a18a upstream.

Realtek Hub (0bda:5487) in Dell Dock WD19 sometimes fails to work
after the system resumes from suspend with remote wakeup enabled
device connected:
[ 1947.640907] hub 5-2.3:1.0: hub_ext_port_status failed (err = -71)
[ 1947.641208] usb 5-2.3-port5: cannot disable (err = -71)
[ 1947.641401] hub 5-2.3:1.0: hub_ext_port_status failed (err = -71)
[ 1947.641450] usb 5-2.3-port4: cannot reset (err = -71)

Information of this hub:
T:  Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 10 Spd=480  MxCh= 5
D:  Ver= 2.10 Cls=09(hub  ) Sub=00 Prot=02 MxPS=64 #Cfgs=  1
P:  Vendor=0bda ProdID=5487 Rev= 1.47
S:  Manufacturer=Dell Inc.
S:  Product=Dell dock
C:* #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=  0mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=01 Driver=hub
E:  Ad=81(I) Atr=03(Int.) MxPS=   1 Ivl=256ms
I:* If#= 0 Alt= 1 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=02 Driver=hub
E:  Ad=81(I) Atr=03(Int.) MxPS=   1 Ivl=256ms

The failure results from the ETIMEDOUT by chance when turning on
the suspend feature for the specified port of the hub. The port
seems to be in an unknown state so the hub_activate during resume
fails the hub_port_status, then the hub will fail to work.

The quirky hub needs the reset-resume quirk to function correctly.

Code: Unable to access opcode bytes at RIP 0x7fe969cf5dad.

Problem occurs for UVC class. During disconnecting the UVC class disable
endpoints and then start dequeuing all requests. This leads to situation
where requests are removed twice. The first one in
cdnsp_gadget_ep_disable and the second in cdnsp_gadget_ep_dequeue
function.
Patch adds condition in cdnsp_gadget_ep_dequeue function which allows
dequeue requests only from enabled endpoint.

usb: dwc2: Prevent core suspend when port connection flag is 0 2021-03-26T13:51:34+00:00 Artur Petrosyan Arthur.Petrosyan@synopsys.com 2021-03-26T10:25:09+00:00 93f672804bf2d7a49ef3fd96827ea6290ca1841e In host mode port connection status flag is "0" when loading the driver. After loading the driver system asserts suspend which is handled by "_dwc2_hcd_suspend()" function. Before the system suspend the port connection status is "0". As result need to check the "port_connect_status" if it is "0", then skipping entering to suspend.
